Review: To help you start - This is just a quick heads up for new buyers; I'll review the product in more detail as I use it. The instructions that come with the sensor are terrible. There's basically a description on how to put the strap/sensor on, but not really anything about pairing to Bluetooth. There are no pairing buttons or switches, the bluetooth and pairing start when you attach the sensor to the strap which contains the electrodes. There are no LED's to tell you that you are paired or in pairing mode. In order to pair you need three things which the instructions, in a sense, tell you. However, the instructions make it seem as if these steps are used to wear and use the sensor, not that it is necessary to follow the steps for pairing. In short, you must: 1) Wet the electrodes (which is the plasticized part on the strap, although the illustration makes it appear that you wet the strap) 2) Place the strap on your chest! This is required because it helps the electrodes to connect, I suppose. Or maybe it needs to receive a heartbeat. In any case, in order to pair, the strap must be on your chest and 3) you need to attach the sensor to the strap (which should be obvious). My Samsung Galaxy 7 (Android) would not find the sensor after a scan until I first installed the Polar Beat app (free) on the phone. I had to use the Polar Beat app to pair the sensor to the phone, it would not pair up using the phone's Bluetooth setting. Once it paired up, pairing with my other app, MapMyRun, was very easy. It would not seem likely that you'd need to wear it in order to pair it, and it would be a lot better if the instructions made that clear. Research on the web also mentioned "keeping it close, like in your front pants pocket". It took me a while to realize that they were talking about the phone, not the sensor. I hope that this helps you in setting up and saving some frustration. One other thing: I have seen reviews where people cannot get the battery cover open without stripping it. Indeed, they say to use a coin to unscrew the cover but since this was designed in Finland, perhaps they are thinking of a Finnish Marrka or Euro coin. In any case, I found that a 1980's era NYC subway token worked fine but that, as others mentioned, a US quarter or nickel would strip the screw slot. So far, with a very light workout, once set up, the sensor seems to work just fine. I compared the results with a hospital quality blood pressure meter and a finger pulse oximeter and the readings all matched, so that part is great. I'll review further as it gets more use. So far, so good. 5 stars with one deducted for poor instructions and lack of a visible pairing indicator. Edit: June 2018 - I've been using this at least 5 hours a week for about 18 months now. I have changed the battery just once in that time; I imagine I'll probably replace it again in another month or two. The strap is washed every time I wear it (I just take it into the shower with me after I run) and it's starting to fray a bit, but will likely last quite a while longer before I may need to replace it. I am upgrading my review from 4 stars to 5 because, despite the trouble I had setting it up and getting a bad unit, it has worked very well and very consistently. I also deducted 1 star due to the lack of a pairing indicator. While this is true (it would be nice to have a light on the sensor) you can tell if it's paired by checking the app on your phone. As regards the instructions, this has been out long enough now that all you need to do is look online and find reviews such as this one and you'll find help if you're having issues setting it up.
Review: I'm glad I went with this Bluetooth device over the "watch" versions! - I originally thought I'd get the wristwatch version of the heart rate monitors (HRM). I'd had a Polar HRM about 10 years ago and it worked pretty good, but occasionally ran into radio interference transmitting to the wrist device - for example near power transmission lines. I could not find very specific information on the details of the wristwatch types in the descriptions on desertcart, and since I am a big guy with a big wrist, I went to Polar's website to find out how large a wrist the devices would fit. I could not find the info there either, but used Polar's Chat feature to ask a question and the customer service tech found me the answer. She gave me the sizes of the chest straps and the wrist straps. The customer service tech measured the FT4 wrist monitor to fit a wrist up to about 8-3/4" maximum. My wrist is about 9". She offered that the more expensive FT40 and RCX5 will fit up to 9-1/2" wrists. Regarding the chest strap sizing, from my Chat Transcript: Nastacia: Our soft strap dimensions are as follows: Nastacia: XS-S: 21-38" Nastacia: M-XXL: 27-60" Nastacia: XXXL: 29-70" (The H7 came with the M-XXL strap, which I found to be smaller than stated above. My chest measures 51" and the M-XXL only fit tightly. I can't imagine it would fit up to 60 inches. So it you are over 48" or so chest, plan on using the XXXL size.) Based on the info above, I went with the H7 Bluetooth model of Polar's HRM's and paired it with my iPhone 5. I'm so glad I did. It works great. I had no problem pairing it and getting going. My partner tried it too, and we found that we first have to unpair the HRM with my phone so she could then pair it to her phone. She liked the H7 so well, she ordered one too. The free Polar Beat app worked well and I like that it maps your route using the phone's GPS. The map feature measures the distance and time and I found it to be very accurate. All of the heart rate data along the route is saved in each session on your phone. You can see how your heart rate changes going up and down hills. Very cool! Once you input your physical details (gender, age, height, weight), the app calculates your max heart rate and records your time in each heart rate zone (e.g., 50-60% of max, 60-70% of max, etc.). It also captures your average heart rate over the session and your max heart rate. I use the H7 for cycling, and the Polar Beat app let's you select from running, cycling, walking, jogging, skiing, rowing, etc., etc. I only wish the app had a feature to display your route vs. the vertical profile (elevation as available from Google Earth). You could then see your heart rate relative to the hills you climb. Overall, I highly recommend the H7.

### ⭐⭐⭐⭐ Hands down better than other Bluetooth Heart Rate Monitors I've tried. Worth the extra money
*by H***O on February 1, 2014*

I've tried the 2 other less expensive Bluetooth heart rate monitors and I have to say this is definitely a better unit. The issue is not so much that the unit actually provides better heart rate data, as I found all the units when working provide approximately the same data, its a reliability, form factor, and functionality issue. Jarv Heart Rate Monitor - Similar design, but much cheaper construction. I was finding that after a month or two the unit will track, but sometimes needs a warm-up period before I know its really tracking. I think the issue is that the electrode pads are not quite of the quality and sensitivity of Polar 60 Beat Heart Rate Monitor - Much sturdier design, but actually a bit bulky and heavier than your average unit. Because you can't detach the control piece I think there's more room for problems. The big issue is that I found it didn't automatically sync as well often requiring manual sync ups which if you forget to do you simply don't get the data. Its not bad though So why did I like the POLAR H7 better. - This unit actually syncs with all standard ANT (that's the name of the protocol similar to Bluetooth) fitness equipment so that in addition to getting data on my phone I get it on the monitor at the gym as well! DO NOT get the H6 Polar unit as it WILL not also sync with your fitness equipment - It actually syncs to both fitness and iPhone at the same time. These are probably different antennas so you can see how well the data matches up. The answer is it matches up very well. In some reviews you will see it commented that there are differences, but that is because most fitness equipment averages several beats to get you a number whereas most bluetooth devices give you the raw data. This means that your fitness equipment ALWAYS lags behind the bluetooth monitor. - Data is very accurate. This is actually true for all belt devices - No warm up period (nice it tracks pretty well right away even after a few weeks of heavy usage) - Syncs automatically reliably. This was an issue with one of the cheaper units I got - Permits syncing of data while listening bluetooth to music. Actually all the devices do, but I put this in so you know its a plus of Bluetooth - You can actually see your data on the BIG phone screen. This again is true for all bluetooth HRMs, but its a HUGE plus for me because trying to read that watch while running is a hazard - Sturdy belt construction. The leads appear to be embedded well and well constructed as expected for Polar - Lightweight. I like this format, because its lighter - Battery compartment accessible. This is important because some devices won't allow you to change the battery yourself - Removable control piece. This works both ways, but the advantage I believe is that you can do a better job washing the belt and I think the battery will last longer. The con is you could lose the control piece CONS - I think I've noticed once in a while that the signal on Bluetooth or ANT drops out briefly. Most software won't show this, but some do and it can be annoying to see a blank screen. Not sure if this is a quirk on software or the device - Directions recommend removing the control piece and rinsing off the belt after each use. This increases the likelihood that you might loose something, but probably improves the longevity
