KKmoon Digital USB Microscope,600X 4.3 LCD Display Electronic Video Magnifier,HD 3.6MP CCD,Adjustable 8 LEDs,1080P/720P/VGA Resolution with Metal Stand Built-in Rechargeable Lithium Battery

I put off acquiring this item for some time until curiosity got the better of me. The idea seems OK and reviews generally positive, so although my expectations weren't high I did think it would be useful. The executive summary: the idea is good but the implementation could do with work.First, the good bits. It is much better than having a webcam or other USB camera wired to a monitor. It's also much less hassle, and less tiring, than a pukka microscope. Being battery powered is worth quite a bit more than one might think too, since there are no trailing wires to deal with. Unlike with a normal stereo microscope, you can see everything around the target as well as the magnified view, so if you've ever tried getting a soldering iron to the right area of a PCB, never mind the particular thing you're going to solder, just so you can see what you're about to melt, this should resonate with you. And you can use this for soldering. The working distance is easily enough to get things between the lens and target, and there is zero lag (that I could detect) between what's going on at the business end and the image following that on the LCD.Also worth mentioning is the stand. It has a nice solid feel (which the microscope doesn't, it has to be said) and despite there being backlash aplenty and a fair amount of play, get the friction knob set right and the image is very solid indeed.But there are bad bits. Where to start? First, the LCD has a very narrow viewing angle, and unless you're looking at it absolutely square-on the image is suboptimal. Unless you sit at a very strange bench, you'll be looking at least slightly down on the screen, and that's enough to wash it out and lose contrast. The result is a very poor image which is massively improved by slouching in your chair. It really needs the display to be tiltable.Still on the LCD (kind of), the lighting LEDs are reasonably OK as these things go but the volume control is in a difficult to reach corner behind the display. It really is difficult to twiddle, and as you do so the display will shake. Mine will find itself acquiring an external pot to make the control useable.Common to all these kinds of lighting, there are no shadows so depth of field is difficult to discern (and, of course, it is not stereo). Adding a side light works wonders and negates the need to fiddle with that awful control. And speaking of controls, whoever thought putting the pushbuttons behind the focus knob so you have to operate them from the side (and still knock the focus out) probably designed the lighting control too.Image-wise, it is so-so. You can see what you're doing and you might think it is pretty OK, but one quick look through a normal microscope and you'll notice how poor the resolution, crispness, contrast, colours, and pretty much everything is in comparison. But against that, this is unobtrusive on the bench and available at the press of the power button. For a quick job it is fine.The final black mark, that got it down to only three stars, is that it is cheap. Given the problems listed above, it should be cheaper, and then it would be worth perhaps 4.5 stars.

Amazing item but failed after 1 month. Seller refused to replace without video proof. Then when proof provided they tried to charge me for the hardware failure. After paypal as involved they sent me a new unit. Buyer beware.

Good product, works very well, but it is the most for the school application.Good for visual inspections of electronic parts and PCB but not for electronic repair under the microscope.The digital zoom is poorly quality it's too noisy.The image quality is not that good, it could be better, it's at the limit, it does not have consistency, the colors are not as vibrant as it should be.The aluminum stand is too small.The incident angle of the camera does not go too well, the camera should be tilted a few degrees further back.I try to read a value from a SMD resistor and I could not do this because of the angle of light falling, and then I pulled the microscope out of the stand and leaned it at another angle for the light to fall from another angle - and so I was able to read the value of the SMD resistance.The backlight is strong and adjustable as intensity.The focus button is the weakest point of this microscope, when you adjust the focus the image moves in the other direction, it does not stay the way you set it.

This is a great digital microscope for the price. The stand is very sturdy, as you'd hope. The level of zoom is impressive, though contrary to some of the box art, you won't be seeing living cells with this!I've used it for inspecting pins on a CPU, and fine soldering work.Being battery powered and usb rechargeable is a huge benefit for convenience.The downsides are clumsy controls, and image panning when changing focus which may indicate misaligned lenses. It's not something that harms picture quality though, you can just use the height adjustment for fine tuning focus.The screen itself is clear from the front but doesn't have great viewing angles.

Works quite well as a microscope, but mine arrived with a broken SD card slot - so quality control is not their strong point. I returned it and bought a slightly more expensive model that hooks up to my phone over WiFiUpdate: The unit that I replaced this with does not have such a good stand as this one. It is as rugged, however THIS model allows the pillar to be rotated. That allows the microscope to be turned so that it is looking into "space" rather than down at the foot of the stand. With something heavy on the base, this would allow a hand-held circuit board (for example) to be viewed from the edge. With the other one I have to remove the microscope from the stand to do that.

on opening this scope i got alot more than what i was expecting. the Quality is second to none, the stand is nice and robust as is the scope itself,the realtime response to the LCD screen is excellent, you can easily solder smd's with this scope. But , and i say but with the greatest respect to the product,but unfortunately i can only give four out of five stars due to the fact that the power supply was faulty. I purchased this for my electronics lab so i had alternative means to charge the scope, so it wasn't a big issue for me, if someone had of purchased this for another use they could have been disappointed. but please don't let this stop you from purchasing this product. i hate the fact that this lovely scope is let down by a lousy power supply.

I got these to use in science lessons at a primary school.The set up instruction were not overly clear and seemed to be for a similar or different generation of the product. The set up and use is fairly intuitive though so this should not be an issue for most people.They are much easier to use than a traditional microscope for younger children and were good for my purpose.The variable zoom, focusing and lighting all worked as you would expect. Overall a good product.
