I've been using this webcam for 3 months and I can honestly say it gives me no troubles. It installs easily and it's easy to adjust the settings. The picture quality is above par relative to the product's price.
Videos are not high-quality, but it shows video as clear as any recreational user could ask. Just make sure you have decent lighting in the room. When evaluating alternatives, I didn't need a high-resolution webcam that sells for 3x the price of this. I use this to communicate via Skype with a friend that's abroad. She has no complaints with audio or video whenever we use it. Overall, this is a good webcam at a great value.
