4K 3840 x 2160P WiFi USB Digital Microscope Wireless Super HD Camera | 50-1000X Endoscope, Compatible with iPhone/Android PC iPad Windows Mac Chrome Linux

This is an improvement over the previous model that was about the same price. See my images of a uk10 pence coin and 2 record deck stylus's to judge the quality of my images. The instructions I found were in small print and you could do with a microscope to read them! Mind you aged 57 I have the same problem reading food labels, etc. Im not a Techie but downloaded the software to my Samsung S21 with no problems. To find the App on your phone it is called WI FI CHECK. It took a while to find it because I thought it would be called Microcope App or similar. Time lag is only a split second so of no issue in use. Be aware, like any new technical equipment dont expect everything to be intuitive straight away, learn through practice how to get the best from the device. This is a piece of scientific equipment not a toy. Give yourself an hour or so to learn the basics, and dont forget to remove the clear plastic Protective Lens Cap! Its great not to have a cable that if you knock you disturb the image. The dials work smoothly. The standard Stand now sticks to your work surface also, to keep things nice and steady. Photos appear in your phones photo library and should appear automatically on your Lap Top. You can then zoom in further, edit then Save if youwant, easy. Video clips can be recorded to! You can buy the basic model for £15 less ...but having the new higher quality 4K model with WiFi connection is well worth it. i'd magine for anyone!

I’ve tried this microscope on various phones using its WiFi connection and various computers using USB, with the phones, it is excellent, easy to connect so long as you follow the instructions, remove the lens cover, (it's clear plastic so easy to forget), turn on microscope, connect to its WiFi then launch the WiFi check app. Connection is limited to one device at a time, I have tried it on Android 13, Android 9 and iOS 15.7.3 and it worked flawlessly, the zoom buttons and photo button on the microscope responded as they should, the image was sharp and it was easy to focus, here I will say that the supplied stand is poor and I would recommend getting a better stand, there are some available on Amazon and they do improve the ease of use of the microscope. Now to using it with a computer, first thing to mention is that you cannot connect to a computer using WiFi you have to use a USB cable, I tried the microscope on three windows 11 desktops, one windows 10 desktop and one windows 10 laptop, it worked okay on two of the windows 11 desktops and both the windows 10 computers, when connected to the other windows 11 desktop it caused the AMD graphics drivers to crash after a few minutes of use, the same AMD graphics drivers were on two of the other desktops that had no driver issues but all have different graphics cards, the highest end one being the one giving the problem, here I’ve got to say the support from the seller was excellent, emails were replied to within 24 hours and although no solution has been found yet the support is excellent. The reason I say it only worked okay on the computers is because the image had a tendency to freeze at regular intervals on all the windows systems I used, not a major issue if you're looking at coins or stamps and such like because changing the focus unfreezes the image until next time but not good if you’re going to be using it for soldering circuit boards, I tested them all using the windows camera app that is the recommended app to use. Another thing to bear in mind when using it connected to a computer is that the buttons on the microscope don’t work. Other things maybe worth a mention is that the USB lead is also used to charge the microscope battery, there is a wheel on the side to change the brightness of the light. To sum up, excellent for portable use, connecting by WiFi to a phone or tablet, okay for occasional use connected to a computer but if you’re going to be using it solely for connecting to a computer then I’d say get a USB microscope. Excellent and quick support available from the suppliers if it’s required.

First thing is first - this microscope is not wireless for a computer\laptop\etc, only a phone or tablet. it mentions this in the product description but I hadn't read it this until it arrived. For a computer you still need to use a cable. Don't make my "mistake". Having said that, as I'm mostly using an old tablet I'm happy with this microscope. I have one of the older wired versions of this. This wireless version with the tablet is much easier to set up and move. The wireless connection does use the tablet wifi connection, so not internet services whilst using it. The "magnification" control wheel it vastly improved. The grey rubber control goes round the entire casing as has a smooth operation. Once have the microscope at your preferred height it acts more as a focus. There are zoom buttons on the side to slightly zoom in\out if required. The build it led ring light is powerful but has an analogue brightness control wheel - better than the 3 brightness levels toggle on the old version I have. The picture is quite good for the price, but can still be a slightly grainy. I've not investigated the full 4k-ness of it to be honest. For the price point it is just the job for my occasional use and worth the extra £8 (at time of writing) over the wired version I have.

The Ninyoon “4K Digital WiFi USB Microscope” offers greater "real life" magnification than many of the earlier so-called 'USB Microscopes' because it has a higher resolution image sensor. That sensor seems to be about 6mm (1/4 inch ?) wide and has 3840 pixels across that axis. ( So this digital microscope device should more properly be described as a “3.8k” (pixels) device [or more precisely as “3.75K”, since technically 1K = 1024 ] ) It is easy to connect and use with an MS/Windows PC when connected via USB cable (supplied) or with an Android or Apple Tablet or Phone via WiFi (which is generated by the ‘4K’ itself). This “4K Digital Microscope” is a cylinder shaped object, about 112mm long with a diameter of 33mm. That contrasts with the F210 (1M pixel microscope) which is slightly shorter at about 110mm and a diameter of 37mm. The 4K unit is decently engineered, providing a smoothly operated focussing ‘barrel’ ring, together with a power on/off button and a ‘star-wheel’ to adjust the brightness of the incorporated LED sample illumination. I strongly recommend the use of the sturdy, decent quality, adjustable metal stand and holder (see photo) which is available from Ninyoon (gratis, if one asks nicely !). The rather flimsy “articulated” holder which has recently been supplied, in a cardboard box alongside the 4K unit, is really rather unstable and difficult to manoeuvre securely. The much better Aluminium alloy ‘ring holder’ clamp and stand permits reasonably fine and stable adjustment of microscope focus and height above the item being examined. Even if you have to pay extra for that ‘Ali’ metal stand, do so. As with *all* digital Microscopes, the size of the image actually observed is dependent on the parameters of the (digital) display screen used - the viewed image size depends on the physical size and the pixel resolution of that screen. Like all modest quality “USB Digital Microscopes” the “4K Microscope” is essentially a “WebCam” with a "Macro" lens system together with an extended (order of 100+ mm) barrel to allow close-up focussing of the object’s image onto a conventional microchip sensor. The higher the quality of the image sensor, the better (within limits). The images observed onscreen (using the recommended software App (‘xploview’) on a MS/Windows PC) can be captured as 'snapshot(s)' or video files, of up to the ‘native’ image sensor capability of 3840 x 2160 pixels. Other software systems (such as Windows 'native' camera software, or other USB camera packages) can also be used with a PC, but with different manipulation and filing capabilities. The images shown via WiFi on an Android or Apple Tablet or Phone (using the recommended ‘WiFi Check’ software App) adopt something of a “trick” whereby the images actually displayed are a subset ‘block’ of the actual scope’s sensor image. Specifically, it displays just a little under half of the sensor capture, presenting images onscreen of 1600 x 1200 pixels (vs. the 3840 x 2160 of the sensor itself). This is to correctly present a high level of magnification on the physically smaller (albeit high resolution) screens of typical Android or Apple handheld devices. But it is also the case that the images (photo or video) that can be filed from these ‘host’ devices are only available as 1600 x 1200 pixels (or, as a ‘WiFi Check’ menu choice, as 1280 x 720 pixels). The 'DM WiFi' software App also works OK via WiFi with the ‘4K’ microscope on my Android Tab, but offers rather lower resolution and is a bit 'picky' about saving images (as ‘jpg’ files falsely labelled as ‘png’ !). In any case, it seems that the 4K scope is not “USB OTG compliant” (or else not “UVC compliant”) and does not support USB connection to Android at all (even if the attached screen devices do themselves support “USB On-The-Go” ). You *must* use the scope’s inbuilt WiFi to connect this digital microscope to Android or Apple Tablet or Phone devices. It is also important to ensure that the 4K Microscopes internal battery is well charged (via the supplied USB cable) before and during use via WiFi connection to a Tablet or Phone. Failure to do so will lead to the onscreen image(s) ‘freezing’ or to losing WiFi connection altogether. A maximum "real world" magnification of about 370 can be obtained (for the image observed on a 61cm (24inch) PC screen of 1920 x 1080 pixels which has a pixel pitch = 0.2745mm ), with the bottom end of the scope unit's ‘barrel’ set at about 20mm from the object being examined. That is to say with the plastic lens ‘hood’ attached and with the focus ring set almost to its max limit, so that the lens assembly projects beyond the bottom of the scope ‘barrel’. At maximum magnification, the 'Field of View’ (FoV) is about 2.8mm. This is really very good – rather more than 3 times the magnification of the earlier F210 scope (which had an image sensor of only about 1 MB). See the attached image xxx_0001 where the dark lines are 1mm apart (images of the markings on a metric Vernier gauge). The maximum *optical* magnification (alone) of the 4K scope seems to be just over 2 (recall that at max magnification the FoV=2.8 mm whilst the image sensor is about 6mm wide). But remember that the image is captured digitally by the "camera sensor" (probably a CMOS 'chip') within the unit, and that digital image is then transmitted to the computer or Tablet or smart Phone to be viewed on a (separate) digital display monitor. Hence the practically achievable overall magnification that is seen, on a digital display screen, of well over 300. When set to its maximum magnification, the 4K microscope has an image resolution of about 1 micrometre (actually about 0.75 micrometre at best), being (FoV=2.8mm) / (3840 pixels). The small, relatively simple optics (about 2mm in diameter with an effective focal length of about 12mm) seem to be good enough to not adversely impact (reduce) that electronics imposed resolution. Except that when set very close to maximum magnification a yellowish colour cast chromatic aberration does seem to intrude slightly. The focussing ring provides about 30mm ‘travel’ of the microscope’s lens system, allowing for the focussing distance from the sample being examined to range from about 15mm beyond the end of the unit’s ‘barrel’ (hence the benefit of the ‘lens hood’) to well over a metre (indeed, almost to infinity! ). That will allow for examination of larger objects some distance from the actual microscope unit. Increasing distance from the ‘sample’ to the microscope body will however (inevitably) result in reduced observable magnification. The third image (xxx_0002) shows the result when the scope ‘barrel’ end is set about 60mm above the sample, giving an effective magnification then of about 40. The fourth image (xxx_0005) shows the magnified view (6mm wide onscreen) of a couple of strands of human hair (brown & grey – mine!), which have a nominal diameter of 50-70 micrometres and thus are seen at a magnification of about 100. The final image (xxx_0006) shows the pistil, stamens and petals of a Common Bluebell, with acceptable ‘depth of focus’, at a magnification of about 65.

Update 02/03/2023: Had to return due to issues. At certain points the output will freeze unless large movements occur over the frame (such as waving a tool in front of the camera). Making it annoying when soldering and unusable for recording youtube repair videos (or any video). The images are still good but as seen on another review, if you zoom in you will see little triangles. It gives a sawtooth/aliasing effect to lines that are not perfectly horizontal/vertical. Could be a faked 4k with pixel doubling, could be auto sharpening artifacts or something. Either way you probably aren't getting the full 4k as advertised in actual usable pixels and looks a little weird zoomed in. The customer service (email) to the company is responsive at least, replying overnight. Tried to pass the freezing issue off as too much reflectivity in the image, but it's no good if you can't look at some items with it. The objects I was looking at weren't especially reflective, just normal circuit boards. Also, you need lots of light to get good images, so bright objects are going to be a matter of course that it needs to cope with. TLDR: Still usable for decent still images (See example pics) but be aware of video freezing issues and pixels problems when zoomed in. Original Text: Quality is actually good. Worth getting rather than taking a risk on the cheapo aliexpress/ebay imports. Takes pictures in actual 3840x2160 4k. Can be used with windows camera app. Focus wheel feels electrically operated as there is a tiny bit of latency when turning but you get a good range that lets you get really far away from the object. Makes is good for soldering. Also make sure to remove the see through lens cap for best quality. Could be left in place to protect from solder flux fume buildup if you wanted. Also works entirely hand held, battery powered, with a smartphone so can be used for blade edge inspecting etc.

Always wanted a microscope, but not sure why. Anyway thought I'd give this a try. Setup was really easy on Android; just downloaded the app, linked to its WiFi, and it just worked with no effort. It's really excellent that it works without any cables (when using my phone). Hands free is good, and the stand is very strong and stable. The image resolution is good and focusing easy, albeit with a very narrow depth of field but for this price you cannot expect the apature control of a DSLR. Great fun to use. Really impressed. Also worked well on PC, albeit with use of the supplied cable. Zoom does not work on PC (as explained in the instruction booklet), but as it's only a digital zoom, that's not an issue;PC software can do that with easy. Overall, very happy with my purchase.

Microscope is pretty good, but let down horribly by a cheap and nasty mount... The screw holding the clamp does not fit the stand. It seems to bottom out before it is tight and the result is a wobbly clamp; no use for a microscope mount. Even trying to loosen the screw is very difficult and I do not want to push it as the screw metal feels very soft. So, avoid unless you have an alternative mount...

Having owned this microscope for a few days now I must say it does not disappoint and comes in at an excellent price point. My other microscope was tethered to my PC by the 0.5m USB cable - when it comes to positioning, the 'Ninyoon 4K WiFi Microscope' really does make life alot easier, as now I can use it anywhere and receive a crystal clear image on my portable device (I'm using an iPhone). The microscope arrived with minimal packaging which protected it well in the post, and can be recycled as its cardboard. First, I tried connecting it to my PC, and following the instructions it was as easy as 1-2-3 and got some very clear pictures of the the handy calibration ruler (which is included) and a very small microchip! (Next to my ballpoint pen for scale) Next, I setup the 'Wifi Check' app on my iPhone and WiFi connection to the Microscope was successful. When I opened the app I did get a blank screen, but this was quickly resolved via 'allowing wifi setting under App Settings' (which is also explained in the instructions). I was up and working within minutes and took a pic and vid close up of my watch face - in excellent quality, transmitted by WiFi to my iPhone, so now I won't be tied down to my PC desk working on soldering components! This was also make working in cramp or odd conditions much easier and convienient, like checking pipes under the floorboads/or reading meters under the stairs, etc.

Den är fantastisk bra och prisvärd!

Ik gebruik de microscoop om planten op plagen te inspecteren en daarbij is het heel fijn dat hij draadloos is en vlot op een mobieltje kan worden aangesloten. Ook de verlichting werkt goed.

Hooks up seamlessly and works great

Niby ok, a jednak to nie jest to czego się oczekuje. Problemy z aplikacją, w zasadzie z jej działaniem. Podstawka mogła by być lepsza, bardziej stabilna. To powiększenie o którym mowa (1000X) to tylko marketing. 4K tutaj raczej nie ma.
