Hand Warmer 2011

I kept this product in my wish list for quite some time and it stayed there for months due to my reluctance to purchase it. I read many reviews saying the fuel was expensive, the catalytic burner was loose fitting, and it was hard to light. For these reasons I began to look elsewhere but always kept coming back to this item. I decided to just go ahead and purchase one along with two replacement burners and a 12oz can of Zippo lighter fuel. The first thing I noticed was how large this thing is. The picture makes it look like the size of a Zippo lighter but it's probably 3 times the size. For my first use I used the included measuring cup and filled it up to the 12 hour mark. From my experience I would suggest just filling the Hand Warmer up straight from the lighter can. It's less messy that way. Lighting the hand warmer was also pretty easy. I held a flame to both sides of the burner for 10 seconds on each side. I turned off the lights just to make sure I could see the orange glow then put the top cover on and placed it in the felt pouch. You can put this in your pockets or under bed covers and this thing will still burn. I have always heard of people saying this is great for cold outdoor weather but it's also great if indoor temperatures are too cold for your comfort. I appreciate it's ability to give me some added warmth in some cold auditorium classrooms I have to sit in. Unless your face is practically touching the hand warmer you and others around you won't notice any odors from the fuel. That's an attribute of any naptha fuel. It's burns hot with low odor so don't worry about using this indoors around others. This hand warmer also burns for hours. I never went to great lengths to measure the burn time but it easily burns for 12 hours. I noticed that the less access the hand warmer had to oxygen the longer it burned. When using this product place it in a pocket. Don't take it out to warm your hands. Too much heat will be lost to the cold environment that you won't benefit as much. Place and keep the hand warmer in a pocket close to your body that is shielded from the wind to maximize your results. Don't worry about the hand warmer burning out, it won't and you'll be thankful for it. If I want to turn the hand warmer off I just pull the burner off real quick and let it cool on a stone surface. I recommend you suffocate the hand warmer in tupperware because you don't want to risk a burn. I've heard that you can buy Coleman lantern fuel very cheaply but Amazon doesn't seem to sell it for the price that others have mentioned. I'll check Walmart or Academy to see if I can find a cheaper source of fuel. Even when you take into account the fuel cost and the cost of the replacement burners this thing still cheaper than what you'll pay for disposable chemical hand warmers. I have already placed an order for another Zippo Hand Warmer. I think people have a point when they say it's best to have a separate hand warmer for each hand in the cold. Update 1: So I went to Academy and bought a 32oz bottle of Coleman naptha fuel for $6 which is great compared to the $8.50 I was paying for 12oz bottles of Zippo lighter fluid. This fuel seems to have less of an odor than Zippo lighter fluid. I've tried Coleman, Zippo, and Ronsonol. I think Ronsonol has the least amount of odor while Coleman is by far the cheapest. All fuels seem to burn the same. I filled the hand warmer to the top of the cotton wadding and I have been seeing burn times over 25 hours. I understand some people new to these types of hand warmers will see the fuel cost as a turnoff but when you experience the burn time as long as these you'll see that chemical hand warmers don't come close in terms of heat output or time. The only thing I don't like is that the felt pouch seems too thick so I find it insulates the hand warmer to much. I think I might make my own cotton pouch to reduce the insulation of the included pouch. Update 2.) Ok so I found that you SHOULDN'T light the burner with a match and I also wouldn't lighter the burner with a Zippo Lighter. I used both of these and thought nothing of it but it seems like you need a blue flame because it doesn't dump sut on the catalytic burner. If you use matches or a Zippo the flame will be orange and cause your burner to turn black with sut buildup. You don't want this. I learned the hard way and had to replace the burner early because I ruined it this way. I now use a cheap Bic lighter and only use the blue part of the flame to light the catalytic burner. It maintains the shiny chrome finish on the burner but more importantly keeps the catalytic mesh material clean. Please please please don't repeat my mistake. I wasted an $8.00 burner when I didn't have to. Bic lighters are cheap as hell and while a torch lighter might work as well because of the blue flame I don't own one so I can't be sure. I also know that regular Zippo lighters have a blue flame but the wind guard obstructs it so I went with a Bic because its blue flame is exposed. I spent $2.00 on a 2 pack of Bic lighters and I am happy with them. It would be great if Zippo lighters worked but I'm not that phased by it. When lighting the hand warmer with a blue flame you may not notice all 6 holes lighting up into an orange ember. That's fine, and normal. Put the lighter aside with the lower half of the hand warmer in the felt pouch and just leave the chrome top of the handwarmer off and leave the burner exposed to the air. After about 10 minutes of being exposed all 6 holes should be bright orange in the dark. At this point put the chrome top cover on and let it heat up for 5 minutes. At this point it will be very hot but it you should be able to pick it up by the bottom because the lower half is in the felt pouch. Zip up the drawstring and enjoy the warmth. I also recommend just buying Coleman camping fuel. It won't burn as hot as Zippo or Ronsonol lighter fluid but it's cheaper. You will feel the difference in how much hotter Zippo Lighter fluid burns but I save my Zippo fuel for those especially cold days. Coleman lighter fluid also leaches the red color from it's red container and will turn the wadding in the handwarmer red. If you want the best of both worlds use Ronsonol. It's cheaper than Zippo lighter fluid but more expensive than Coleman but Ronsonol burns just as hot as Zippo Lighter Fluid and is clear as well so it won't dye the wadding. I hope I helped anyone thinking about buying these. They're a great product but I think Zippo isn't clear about how to best use and maintain the product. Feel free to ask me any questions.

I've read most of, if not all, of the Amazon reviews on this product. I've also read most of the reviews from other websites and magazines. I decided to purchase this warmer because I am a cheap person. I don't like disposable things, especially expensive disposable, wasteful hand warmers. I was a little bit hesitant about taking every thing I read at face value. Well, upon receiving it, this hand warmer has exceeded my expectations in every way that I've read. First off, I've read countless times that this hand warmer is so hot that without the bag, it is impossible to hold because it is so hot. TRUE. Right out of the box I was skeptical because it wasn't running very hot. The instructions say to run the first cycle with twice the measured fuel. Well I guess it took about three use cycles to break in the catalytic burner head, because now all of my skepticism is completely gone because this thing runs HOT. When you leave it out of its little baggy (for a couple of minutes to let it warm up to the increased Oxygen) it is very uncomfortable to place against any part of your body or face. Just like touching a hot pan. You can only hold it in your hand for about 5 seconds before you have to drop it. Unfortunately, when you put it in its little baggy, it barely feels warm. Again, I was originally skeptical about this claim, and I was anticipating that the reports were exaggerated or posted by people with low tolerances for heat. I have a pretty high spot tolerance for heat, and I am still suffering from the immense heat of this warmer. This also won't happen on the first light-up, like I assume most negative reviewers assumed. It will take probably about 30 hours of continuous burning before the catalytic head is broken in, and then every time you light it up afterwards, it will heat up to this temperature in very little time. Less than five minutes. If you leave the warmer out of baggy for about an hour, then it will be completely intolerable to touch. You can't even pick it up without your brain immediately telling your fingers to let go as a natural reflex. Fortunately, when you place it in a pocket, without the bag, it is exposed to limited oxygen so it burns at the exact perfect temperature. Still very hot to the touch, and your friends will be impressed at how much hotter it is than those heavy disposable things. But it is also not to hot that you can't hold it in your hand indefinitely. For most of the time you're using this device, it will be inside an article of clothing like a jacket pocket, shirt pocket (this is the winner here) or even glove (kind of bulky but it gets the job done). This keeps it at the perfect temperature. No need to worry about it being too hot or too cold. It is also impressive how long this hand warmer lasts on a single filling. Obviously, the less oxygen it gets, the longer it lasts on a single filling. I haven't done any timing specifically, but I can tell you that when I fill it up (I don't use that plastic cup, I just fill the thing directly until it looks like the rayon batting is saturated) it lasts for about a full day. Using the cup at full, I typically will get well over 12 hours. Probably around 15 hours. In case you were wondering, the whole bottom of the hand warmer is NOT the fuel container. It is actually a much smaller reservoir that is simply set inside very tightly. It is not removable without special tools as I believe there is some heat resistant adhesive holding it in place. The actual fuel reserve is probably about 2-3x the size of a simple zippo lighter's reserve. The lighter does have a pretty strong petroleum smell that can be smelled within about 6" of the lighter. This is amplified by putting it in the little baggy, which I assume holds the odor like a sponge. Without the bag the smell is only about 2" away from the lighter. If it's inside of a pocket of a jacket, I'm sure it won't be a problem for most casual hunters or bird watchers. Yes, lighting this warmer can be difficult. Not actually difficult, but just time-consuming. I usually hold it upside down over my Zippo for ten seconds even. This almost universally gets it going. I've found that the longer you leave the lighter on, the faster the warmer will heat up because you get more of the burner head catalyzing. A good solid rule of thumb is that if you actually light up the burner so long that it has its own self sustaining flame, put out the flame and you're good to go. You don't actually need to see the flame to get it going, however, and I'm not sure of the consequences of this action as far as the health of the burner is concerned. After you use the burner for a while, it gets easier to light up, so again, don't be dissuaded by the first lighting attempt. Another thing, if the warmer is really cold it sometimes helps to hold the whole bottom half of the warmer over the flame for ten to twenty seconds to warm it up. This burner relies on its own heat to vaporize the fuel to continue the reaction, so the hotter the fuel container is, the faster it will light up, and the hotter it will burn. The plastic cup is rubbish. It's like a siphon thing and you can't control it very well, so it overfills way to quickly, and you end up getting half your fuel all over your hand and the warmer, rather than IN the warmer. I lost all the hairs on my left hand doing this... Now I just pour the fuel right from the can (or the Ronsonol bottle, or with a funnel from a small bottle of White Gas like Coleman Fuel, which is naphtha, exactly the same stuff as the Ronsonol fuel, and similar to the Zippo fuel, but at $8/gallon, vs $6/12oz.). When you see the rayon balls get soaked, then you know you have about "12 hours" of fuel, so like 15 hours and counting. Using this method, you can fill the warmer up to the top, and to well over a full day of heat OUTSIDE of the baggy! The only adverse affects of filling it THAT full that I have found so far is that if you can actually see large amounts of liquid (rather than just soaked rayon balls) then burn off the first 5-7 seconds of fuel until you can't see a layer of fluid on top of the rayon batting, otherwise it will be too wet, and directly put out the burner head by soaking it if you tip the warmer over. (Note that the fuel still won't spill OUT of the warmer, which is good, so you can transport it with extra fuel). There is no actual flame, so you can safely place it on a carpet or in your pocket without any risks of open flame or whatnot. It doesn't even get close to the temperature of an open flame, so it's really safe, just as safe as the disposable Hot Hands warmers. There is no flame or even embers or sparks, so you can't even light a gas stove with the lit hand warmer, just to tell you how safe it is. That's not to say that I would recommend this in any potentially hazardous or explosion danger situation or area like areas marked "NO SMOKING WITHIN 100 FT." At least not if the burner is exposed to air, and not tucked nicely into a glove or pocket like it should be. Better to be safe than sorry. That said, the reaction can be stopped, easily, in multiple ways. 1. For immediate emergency OFF, douse the burner head in water or other liquid. This will take the heating right out of the warmer. The easiest way, I have found, is to place the warmer in a small Zip Lock bag and wait for about three to five minutes to starve of oxygen. The best way I think is to simply remove the catalytic heating head with your finger nails or the edge of the warmer cap and let it sit for about 30 seconds. Then you can light the thing right back up again when the need strikes you. On that note, I will leave you, my fine Amazonians, to purchase this amazing product and test it for yourself. Please feel free to leave any comments with questions or concerns. Sincerely, Esteban Valle

I bought two of these for hunting. They work fabulous, as they should be since this technology has been around for decades. A few things I noticed that potential buyers might want to know about: Contrary to what is advertised, my units do not operate for 12 hours when filled "fully." So far, they actually burn for closer to 20 hours! I have only ran my units three times, so maybe this will change over time. Manufacturer says you cannot put them out once lit. NOT TRUE. These run off of an oxidation process that uses a platinum catalyst to slow combustion by over 50% (creating a glowing catalytic element that produces heat), so they run off of oxygen, like a fire, they just don't burn or have a flame. So, simply cutting oxygen off will put them out. They can easily be re-lit, unless they are relatively low on fuel, which you can fix by simply adding a few drops of fuel directly onto the catalytic element, and if that doesn't work, just top it off with fuel a bit. These are advertised as hand warmers. Yes, they keep your hands warm, but they are not small enough to fit in most little pockets on gloves. They work great in a hand warmer tube for hunting, or to simply put in an inside pocket. One drawback, which can be fixed by just learning more about how these things burn through trial and error, is the fact that they seem to not get quite hot enough while in the little pouches, but they get too hot when out of the pouches (i.e., they get enough oxygen out of the pouches to get too hot to the touch, but inside the pouches the oxygen exposure doesn't seem to be quite enough for significant heat). You need to strike some balance with the level of oxygen these things get. Using them inside the pouches while also being inside a coat or pocket will likely cut off oxygen too much, so you can probably just use them without the pouches as long as they're not exposed to open air, leaving the only use of the pouches for sitting them on tables when you're not using them (where, you can also just put them out). You just have to get to know how they work and burn in regards to oxygen exposure. Apparently, there is a break-in period for these things, which can change most of what I just said above in regards to using the pouches. The first time I lit them, they took close to an hour to heat up, even when uncovered. Now, after a few uses, they seem to heat up much quicker, and light up much quicker (at first, it was hard to get the catalytic element actually glowing, sometimes you need to light it more than once). After a few uses, they light up with ease, and heat up quickly. Lastly, I send out a WARNING: ONLY LIGHT THESE OVER A SURFACE THAT WILL NOT BURN!!! When I first tried mine, I followed the directions and filled them up double the amount (says to do that upon first use). This causes the filling to be saturated with fuel, which is fine, but when I did it, it was just slightly too much and must have leached up into the catalytic element. When I lit them, they did their usual 4 inch flame, which should simmer down to just make the element glow from a catalytic reaction, not full blown combustion; however the flame kept burning, until they actually got too hot for me to hold in my hands, so I dropped them, and when they hit the floor they actually spilled fluid on the floor (because of how full they were, the fluid came through the catalytic element/top), which immediately ignited all over the floor. Since this was on my garage floor, I was able to smother them out, no harm done; but if this was inside the house, on wood or carpet, my house would have very likely burned down. I light them in my house now, as I have a better idea as to when they would be overfilled, but I do it over the sink. Case in sum: don't light these things over a surface that will burn if you drop it. Use extra caution the first few times you use these things. Overall, EXCELLENT product. I only gave it 4 stars because they have a limited application given their size and the fact that they burn on fuel (so there's an added element of caution that must be exercised that's not present when you use the disposable ones, plus you probably can't take them on a plane, etc). The tradeoff over the disposables, however, is the fact that these things run close to three times as long, and they're so cheap to refill. They literally pay for themselves in about 5 uses!

There are lots of positive reviews and a good number of negative reviews, so thought I would add my experience - positive and negative with the product and some troubleshooting tips. TROUBLE SHOOTING TIP(S) Addendum: If your handwarmer isn't staying lit or not burning as hot, in addition to the wick trimming trick noted below, take the catalyst and over a gas stove or butane lighter, heat the catalyst until it glows red hot (the fibers on the removable metal piece on top of the hand warmer that you light). The wick trick helped, but the catalyst wasn't heating up to where it should be. This trick helped a LOT. As others have noted, it gets better with age, I'm assuming there is some sort of residue on the original catalyst or that builds up if it isn't burning properly (like carbon or something) which accumulates with time. If burning properly, I'm guessing it burns off this stuff-hope that makes sense, and is just a guess. But those two things help or seem to fix the problem. Good luck! POSITIVES: Keeps me warm when I'm standing at the dog park in the winter - hands and body keep warm. I put one in my inside pocket of my coat and one in my outside pocket. Generates quite a bit of heat. If you take it out of the protective pouch (with plenty of air) it will get very hot - as in don't touch it hot, but will keep you very warm. Cheap to buy and own. I like being able to reuse it everyday and it is a cheaper and warmer alternative than those sand filled type hand warmers that you shake. (I do use those for my feet, though, and put them in my boots.) So with the two products combined, keep quite warm. Fairly easy to use, but can be messy (see Cons). CONS: Messy to fill and the accompanying fill cup and funnel is pretty useless and in fact dangerous as you will spill lighter fluid on yourself and the hand warmer. The hand warmer did flame up a couple times using that method - but I was using our gas stove to light it, which is a bad idea. (seemed like a good idea at the time). If you use a butane torch type lighter or stove, you can heat up the wick enough that it hardens like a rock. This will keep the flame underneath the catalyst from starting, regardless of how much fuel you have in the hand warmer. I'm guessing this is a problem for some people whose hand warmer 'stops' working after awhile - it did with mine. TROUBLESHOOTING SOLUTIONS: If your hand warmer isn't working as well as it was when you first bought it, try poking at the wick inside the warmer. Is it hard on the top? Pull it through with a metal pick and cut off the part that has hardened and then fluff the wick and try again. As in the video, upon first use fluff the wick up a bit. If you filled it with the filling cup that comes with it, did you push the wick down so as not to spill the fluid? You might have pushed the wick down too far, pull it up a bit so its at least flush with the metal grate at the top. * Skip using the filling cup and guesstimate fluid. You'll get better guessing with time. ( you'll just spill fluid using that idiotically designed cup). * Press down the wick with the Zippo lighter fluid can, using the tip of the filler to press down - this will help to not spill lighter fluid on your handwarmer or hands, dangerous. * Handwarmer doesn't work outside. Make sure its getting enough oxygen. If I put them in my front jean pockets, it will extinguish the hand warmer. If its exposed directly to the cold (outside pocket), I do believe if its cold enough outside it will extinguish the small flame. I put my handwarmer in my inside coat pocket and leave the pocket unzipped - has always been quite warm. While I'm sure the company won't advise this (and I'll say it with GREAT caution), I just leave the handwarmer out of the bag and put it in my pocket. Be CAREFUL, it will get very hot, not quite burning yourself hot, but enough to hurt if you grab onto it. * As far as extinguishing it, I put it in a SMALL tupperware box and close the lid, that seems to work. In the video the guy pops the catalyst off in his hands, I would NOT do that, it is freaking hot. Hope that was helpful. I'm not sure about the one star reviews, I'd like to see what they were doing and how they were lighting the hand warmers, as its pretty simple - I mean really simple and straightforward. I've recommended this to several people - who have purchased them - and they have had zero problems to date. * ADDENDUM: Also found that if you don't use the measuring cup you can overfill the hand warmer. Experiment with it for further troubleshooting and found that if you overfill it, light it, and turn it on its side or upside down, the fuel will not vaporize and actually extinguish the flame. So, in this case you'll probably want to leave it for a day or so before trying to light it again. What worked for me was to light it and hold the hand warmer upright until it was hot. You can see what I mean if you think you've overfilled it, light it until it glows then flip it upside down with the cap off, you'll hear it be extinguished by the fluid (vapor is what burns, not fluid).

I own half a dozen of these, which I put (1) outside overnight in the nests that the neighborhood cats make to get through the winter, and (2) in my bed, to keep my feet warm in the winter. I also highly recommend keeping two of these in your car as an emergency item for the winter. Disposable hand warmers lose their potency over time (disposable ones are stamped with an expiration date) and if you are really stuck somewhere on an icy road, you want this item for sure, not the disposable types that give off not even half the heat of these Zippos. Of the half dozen I own, most light very easily, but one is very stubborn in maintaining heat in the "burner", so I find myself having to relight it. Once it's lit, it's lit, and it will stay lit for 12 hours, 24 hours, whatever (depending on how much fuel you have inserted), but getting it started requires attempting to light it, letting it sit for 5 minutes, then seeing if it is hot, and re-attempting if it is not. It is impossible for it to suddenly click off in mid-burn, so the annoyance is limited to that very first five-minute period-- once it gets going, there is no need to check later to see if it is still hot. To repeat, 5 of the 6 I own have none of these issues, it's just 1 of them that does it. Despite that annoyance with the one (which could be fixed in 30 seconds by buying a replacement burner Zippo Outdoor Line Handwarmer Replacement Burner (Silver, 2.38 x 5.81 x 5.31) , also available here on Amazon), this product is excellent. It generates an incredible amount of heat and burns for a very long time. Moreover, it's safe for pets and small children. If you get cold feet at night, toss one or two of these in under the blankets at night. You'll be genuinely impressed in the morning at how warm that part of the bed is 8 hours later. It seems that you can buy a single box of 40 disposable handwarmers or 3 of these Zippo reusable ones for the same price. By all means, get these Zippo reusable ones. You'll save oodles of money in the long run, for twice the heat-generating capacity. [Edit/update #1: I now own about 15, maybe 20 of these, mainly for my animals, and I've found that only one of them has had an annoying burner that doesn't light. The rest have been fine.] [Edit #2: Want to save on your electricity bills this winter? Get a Teton -18 or -25 degree sleeping bag, such as this: TETON Sports Mammoth Sleeping Bag or this: TETON Sports Celsius XL -32 Degree C / -25 Degree F Flannel Lined Sleeping Bag (90"x 36") and about three of these Zippo hand warmers. You can sleep in a 40*F or 50*F room in just your underwear (or less!) and actually be HOT-- no other blankets needed (although the air inside your box spring mattress might be too chilly for comfort-- in that case, you might need an electric blanket underneath (outside) the sleeping bag to warm it up before you get in. Dare to set the thermostat to "just high enough to keep the pipes from freezing." Amazing product, Zippo!]

I remember seeing these when I was a kid and thought they were really cool, I didn't realize there were companies still making them! There are several brands out there, I went with the Zippo simply because of my experience with them in the past. I've only had this for a day and I'm already very impressed! I lit mine at about 9pm last night, it is now NOON the next day and it's still going and very warm! 15 hours so far! I may have overfilled it a bit. The filling cup it comes with is a major pain to use, kept spilling everywhere, so I topped it off by just squirting directly from the bottle. I had no problems getting mine lit, held a lighter over the element for 4-5 seconds as the instructions said, worked great. It is VERY hard to tell if it's lit, you just have to wait for a few minutes and cup your hand over the element to see if it's starting to get warm, or take into a very dark room, where you can faintly see a red glow coming from the element It does have a bit of a kerosene smell to it as it burns. Not very strong but it may bother some people. I put it in my inside jacket pocket and every so often would get a whiff of it, didn't bother me. I should also mention that the instruction booklet says that the heating element does burn out eventually. It is supposed to last 70-80 uses, replacements can be found on Amazon for about $8. Overall great product, I'm very satisfied! This will work great for cold hikes or hunting trips!+ **Update** I've had these for two winters now and they still work GREAT. Awesome for cold Saturday mornings at my kids' football games. Had to get a couple more because my wife & daughter kept stealing mine. The booklet does not recommend doing this, but you can remove them from the bag and they will get much, much warmer. They're a little too warm to use on bare hands this way, but placed inside your inside jacket pocket they do a fantastic job keeping you warm.

The temperature here has been getting in the 30-40s and I work in the elements so I've been wanting to get a re-usable hand warmer. After reading reviews and looking at the options, the Zippo warmer seemed like the way to go. I got the warmer, used zippo brand fuel, followed the directions(as easy as they are) and have not had luck with this warmer. I have been experimenting with it and have no consistent luck with making it work. Using zippo fuel, zippo lighter and following the instructions the warmer works perfect in my house and will stay warm for over 12 hours no problem. However, following the same procedure and then taking it to work in colder temperatures it fails to stay warm and the burner goes out within minutes. I've tried different brands of fuel, using different lighters, letting it heat up with and without the pouch, keeping it in a pocket and sitting out in the open. Nothing will keep it ignited while at work where I need it. No combination that I've found seems to work outside of my house. Igniting it an hour before going to work didn't help. Leaving it out of the warming pouch for the first hour didn't help. Trying to re-ignite it while at work is a pain and I've tried so many times and it just will not stay ignited. I can see the burner glowing read and put the cap back on(tried with and without the pouch) and it will go stone cold within a few minutes at work. Trying to explain to co-workers, why I am holding a zippo lighter to some camouflage device is hard enough but then to not have it do its job makes it worse. It's an awesome hand warmer, if you don't plan to use it in the cold.... I've tried everything I can, watched every youtube video showing how to use it, tried every type of fuel I can and lighter I can, combination of igniting it and I can't make it work outside of my house so, 1 star.

The concept of this product is great, but after one use it is ok. Before i bought the item I was skeptical about having something I light on fire (to get it started) and maintaining it in my pocket. After watching YouTube videos it seemed like a good purchase. The first use... Filling the warmer is a pain using the little cup from the packaging. The little cotton area doesn't soak up the lighter fluid quickly so pour it slowly. Also recommend laying down some newspaper OR pouring the fluid over the sink so it doesn't make a mess. Once filled it took a while to get the catalytic burner going. Hold the flame for more than 5 seconds. But once the catalytic is lit it warms up quick. It is not hot enough to carry within the pouch, yet too hot in my bare hands. The warmer emits a faint burning smell. If it is not oriented in an upright position leaks. This is more of a novelty item than for everyday use.

このモデルはバーナーエレメンツがUSモデルである為、ZIPPO他モデルとの互換性が無い事を明記すべき。 リピートですが勉強になりました、クォリティに不満はありません。

Te calentará las manos increiblemente rápido, hasta el punto que si no le pones la funda, te quemarás. Dura 8 - 10 horas con carga al máximo de gasolina de mechero. Ten en cuenta que, la cabeza por donde lo enciendes es un consumible y se gasta y que, cada recambio te saldrá entre 6 - 10 euros dependiendo donde los compres (sin contar envío). Es un punto muy negativo...

とにかくあったかいです！ 付属のフリース袋に入れてないと、熱いぐらいです。 デザインもかっこいいですし、買ってよかったです！ ちなみに、ZHW-JHGとは火口の作りが少し違います。

Simple. Easy to use. Works as advertised. Bought 2 of these for my girlfriend who always has cold hands and feet from fall to spring. She absolutely loves them. Uses them inside sometimes in our draughty apartment. A little tricky to light the first few times, but gets better as the filament works in. Now I can do outdoor activity with my girlfriend without her getting cold hands/body. You can put them in your coat pockets or inside shirt pockets to warm your core. I recommend for anyone who gets cold during any type of activity.

I was a bit skeptical at first, I'm a purist, if I have cold hands I'll put on some gloves. However, this is a quality product, it's so good I want to give it a name. Although in my case it did not work properly right out of the box, at the time I suspected this may be because I received a sub standard burner so I ordered a replacement. The hand warmer stayed lit on the first day for about 6 hours, not too warm. 2nd day it went out every hour or so in my pocket and had to be relit. It didn't last the 12 hours its supposed to. The most I got was 9 hours. I'd suggest to anyone thinking they may have acquired a faulty one to order a replacement burner. I didn't have any problems lighting it aside from the time it took to do so with a standard flame. I started using a jet flame lighter, not sure if that's ok but the burner seems to like the blue part of any flame best so it seemed like a good idea and works much quicker. 1 burner is supposed to last up to 70 uses, I'm thinking maybe the jet flame reduces that. Its still experimental right now so I don't know. The fuel delivery system is not too good, you have to be careful or its a messy experience. Some of the reviews of this product on youtube show a different style of opening for putting fuel in, which looks a lot easier than what I have on my hand warmer. I can only assume that these were earlier models. The Peacock hand warmer seems to be the best of the bunch. Essentially its exactly the same as this, even made in the same factory by all accounts, but the delivery system for the fuel is much better. For the Peacock you clip the measuring jug to the opening on the burner, fill the jug and then when you rotate it this opens a little valve at the bottom of the jug which releases the fuel, not a drop spilled. I can only assume its patented or something and that's why Zippo can't do the same thing. Also on the box for the Peacock it clearly states that you should light this with a match, I did try about 10 matches and to be honest they were utterly useless. There is one video on youtube where the lid on the Zippo hand warmer has a little strip attached to it which you can press against the burner when lit, the strip turns red to indicate that its properly lit. This is something I do not have on mine, didn't work too well for the guy in the video so I assume Zippo have dropped the idea. By the time my replacement burner turned up, the original was refusing to light at all. I could see the difference just looking at them together. Since I attached the new one the hand warmer has been working fine. Infact it's working better than advertised. I'm getting 20hrs of heat for a 12 hr refill, about 12 hours for a 6 hour fill. My Zippo fuel canister which holds enough to fill a lighter will give out 6 hours of heat. I am not sure exactly how quickly fuel evaporates when its not being used. It would be great if there were some sort of seal which prevented it from doing so when not in use. 1 standard 100ml can of fuel will fill this 5.5 times to the max, for the 6 hour burn that's 11 fills per can. I'd recommend this product if you live in a cold climate, or if you enjoy outdoor wintery activities such as snowboarding, or even if you find yourself all too often freezing at a bus stop, not much use anywhere hot though.
