Jiusion 40 to 1000x Magnification Endoscope, 8 LED USB 2.0 Digital Microscope, Mini Camera with OTG Adapter and Metal Stand, Compatible with Mac Window 7 8 10 11 Android Linux

This is an easy 5-stars for me. The price is amazing and it works extremely well. Ok, it's my first microscope so maybe I'm easily pleased, but it captures very good images at high magnification. Best of all for me is the fact that you just hook it up to your PC (it's plug and play, so just plug it in to a USB port and then turn on the 'Camera' app that comes with Windows) and you see the images on the screen instead of having to look into the microscope itself. This is really handy, it allows you to press the camera against your skin, hair, clothing etc and just look at the screen. The cable is long enough for it to reach from my PC, which is on a desk, down to the carpet. Then you can just hit 'Print Screen' and save your images in a paint package. I've had loads of fun with it and for £30, you just can't go wrong.The only issue I had, being a microscope noob, is that I couldn't work out how to focus it properly. A little bit of reading later and I realised that this an issue with all microscopes and it's due to focal length etc. It's not really a problem though, press it up against your subject and alter the zoom until it comes into focus. I find that for most subjects, I get clarity at two different zooms, one giving a good overall close-up and then it goes fuzzy until it comes into view again for a much more zoomed in close-up.

The microscope worked perfectly out of the box on my Android phone, laptop and desktop. You can just plug it in and use it like a USB webcam or you can download their recommended software which worked perfectly and easily.It has two main zoom modes, the lower magnification one has quite an impressive range and let's you place the microscope a reasonable distance away at the cost of magnification. It also has a higher magnification mode that works only when the thing you are trying to look at is right at the end of the microscope.The scroll wheel on the cord for the LED brightness is very useful as you don't need to touch the microscope to change the brightness which means you don't accidently move it.I have used mine for just generally looking at things, smd LEDs, E-paper displays etc. It is powerful enough to look at the pixels on your phone or monitor. I have also used it for smd soldering where it's long range came in very helpful as I could keep the microscope at a distance whilst using a hot air reflow gun whilst still having the benefit of the magnification of the microscope showing on a large screen. After soldering I could use the higher magnification mode to inspect the individual solder joints. The microscope coped comfortably with applying solder paste and components of 0402 size and qfn44 and I am confident enough in its ability to try smaller and more dense packages.Overall brilliant scope, very easy to use and works very well.

It works adequately on my Jiusion USB microscope (which is hopeless without such a stand). It is aluminium (including the drive rack) so it will not be especially durable, but probably adequate for home use. The machining tolerance on the rack is terrible (wobbly), but the clever design of the friction clamping screw means the looseness of the adjustment does not translate into a wobbly held position and the microscope is easily focused.The adjustment range is quoted as 0 to 7 inches (0 to 18 cm). That is a blatant LIE, which annoys me. The length of the milled rack is 4½ inches as a generous measure (4.4 inch). They have measured from the flat top surface of the stand to the top of the vertical post. That is not the adjustment range! Sure you could loosen the clamps on the microscope body, but that should not be counted as “adjustment range”. Wind it to the bottom of the rack. Call that zero. It then moves 4.5 inches as a maximum. That is a long way from 7 inches.It does a reasonable job at a good price. It loses a star for lying about the spec.

The Jiusion 2K HD 2560x1440P USB Digital Microscope looks very much like the scope I had before - no brand name. Wanted a replacement because software no longer worked (less than 2 years old). Thought maybe a windows update may be responsible. Tried everything but could not get it to work.This microscope looked so similar to the one I had and was not sure it would be any better. Eventually decided to take the plunge and boy am I pleased I did. Arrived within 48 hours with a good instruction leaflet with info to download software (xploview installation package) which I did. Up and running in no time.The picture quality way better than my last microscope due to its HD resolution. Lights controlled by a rotary switch on cable is much easier to use. Not always needed but nice to have when a dimmed effect is required. Usual button for a snap picture and a light weight stand - usable but probably the weakest part of the package. Also includes a Microscope Micrometer Calibration Ruler which I'm sure will come in handy at some point.Using it for printed circuit boards and coins mostly but it has also helped me replace a tiny screw in my glasses. Must be tons of ways this microscope can be of assistance.To conclude, this USB microscope from Jiusion is great value with good build and picture quality and this on a 27in monitor and running windows 10. Excellent.
