The LifeCam Studio HD webcam is well made and is positioned securely on the monitor. For my claims, however, the autofocus is very slow / sluggish and in dim lighting I find the image too noisy. Originally I wanted to use this camera as an alternative to built-in webcam in my iMac, but I am quickly strayed from it. In good light, the camera takes clear shots; but that ultimately make most cameras. The built-in microphone, I found very insufficient - and somehow noisy reverberant!
