Had this webcam now for about 7 months and really cannot fault it.
The video quality is fantastic, it very very rarely freezes or sticks and it looks great!
You can attach the webcam to your monitor / laptop very easily, it is sturdy and doesn't fall off or move when you are using it.
Compatible with ALL messengers including MSN, yahoo and skype... It does have an autofocus feature and people are always commenting on how sharp my video is!
Its very easy to use and to set up and also comes with some rather nifty software for taking high quality pictures and videos as well as editing them etc.
In my opinion this is a total bargain as it is really cheap for the quality you are getting. To get a webcam with such high quality video you generally pay a lot more so I very highly recommend for those of you who don't want to pay too much!
