Summary: I had to replace a desktop and it came with Windows 8. None of my on hand webcams were compatible--none would work. I guess we can say they call it "8" for the number of people that will have compatible equipment. I searched on Amazon for a cam that would work. This was one of, if not the least expensive one in the list. I did not recognize the brand, but purchased it anyway. You get what you pay for. It worked-but the picture was not as clear and crisp as I wanted.
Summary: I gave this one a try because it is smaller than others I have tried, but I could only get it to work with Mac OSX, and even then the picture quality is poor. In Linux, the colors are inverted and picture is distorted. Other reviewers said it worked for them, so maybe I got a lemon. You can get a reputable product from an better-known brand (Logitech C270) for only a few dollars more; I'm going to switch back.
Summary: I noticed that the cord was shorter than usual. I moved my computer around to make it work. The webcam hinge doesn't sit on the flat screen computer monitor very well. I fiddled with it for while until it stayed. Finally, the contrast was off. I was orange. Maybe I could fix this through software but I'm a computer novice and it would take too long to figure out. Something different about this that I liked was the view was wider.
