Great Developer Support
I purchased this to change settings on my Logitech C920 and initially had issues with it detecting my camera. However, Liang-Hsin responded within hours and helped me diagnose the problem (turned out to be some bad Matrox drivers). The upside is that FaceTime, which has been broken for months (probably since I installed the Matrox drivers) now works again as well. :)
Also tested it with my several year old Microsoft Lifecam Studio and it worked great. It is awesome to finally be able to fully use high quality webcams with my Mac!
