I bought this webcam because I wanted some HD footage to upload to video websites, including youTube. After reading many positive comments on this Microsoft product, I decided to buy it, and I wan't disappointed.
The biggest obstacle is getting into the box. The packaging is so complicated I wonder if it was designed by the same engineers that designed the webcam itself. Following the instructions, installing the webcam on my Windows 7 PC,was a breeze, with no problems.
The picture quality is superb, the audio is sufficient, though if you are fussy, you will want to record audio with a separate mic, but for general stuff the built in mic is adequate.
If you want a good quality HD webcam at a very reasonable price, you can't go wrong with this MS HD webcam.
