Summary: If you have a desk top, without a web cam, this is the solution. Works well with skype, facebook, Microsoft messenger and a couple of chat clients. may well work with many more - On a PC it has many functions, on a mac it is a webcam. nothing special. But. I like it, takes good pictures and I have nothing but compliments on the audio quality from its own microphone.
Summary: Long distance relationship-ers, rejoice! This webcam is perfect. You really do just plug and go! The image quality is great and the sound is superb. I can talk normally and my fiance can hear everything perfectly. The noise cancelling feature is also pretty great. The way it sits on top of your laptop makes it universal. I was afraid it wouldn't work, but trust me, it will. Don't spend anymore than you have to for a webcam. This is just perfect!
