Review on CISNO USB Digital Microscope: 2MP, 1000X Magnification, 8 LED, Windows-Compatible by Dustin Ramsey

I expected the quality to be low based on the price, but it doesn't work at all. It worked intermittently when I first tried it, but would constantly lose connection with the computer. I gave up for a few weeks before trying again and on my second attempt it died completely. LED lights come on but computer won't recognize the camera. I've tried several computers and have the same problem on each.Also, it should be noted that even though the zoom can be adjusted, the focus can't. You have a fixed point of focus for each zoom level, which means anything microscope distance is going to use the lowest zoom level. The higher zoom levels would only work for objects far away (like telescope distance).Unfortunately, I took too long to realize the product doesn't work at all so I can't return it. Don't even bother ordering - this is an absolute waste.
