The camera delivers very good, sharp image even in low light and runs fine with OS X. There's an app Logitech to set focus, white balance, zoom, and other parameters in the Apple App Store. The built-in stereo microphones are also very good. The Auto Gain Control is well balanced. The holder is stable, valuable and flexible enough to attach the camera eg on a microphone or camera tripod. The best webcam that we have ever had. We recommend.
