Over the past 15 years I have owned about 15 different webcams froma large number of suppliers. The c910 from Logitech is the finest one I have ever used. The Unit easy affixes to most flat screen monitors but on some can extend a bit down onto the actual display. Installation was a bit slow but very easy with the included CD. After install the camera was plugged in and ready to use in minutes. The included VID software from Logitech required a upgrade that downloaded automatically from the internet. The video quality is high and the recorded sound is really amazing. As expected, you need a fairly fast computer to handle the HD output of the camera and a large display to show it. My system is an I7 Intel and works very well but my older laptop could not handle the output. Much better sound and pictur than the Microsoft lifecam Cinema that it replaced.
