An excellent webcam

As soon as received, immediately assembled and tested. You must download the driver software and internet (it is well explained in the little Logitech guide found in the box.)
Installation could not be simpler.
Picture: HD sharpness is superb and correcting copy colors. The image is "wide" 16/9.
The sound: stunning sharpness. Tested with a corresponding Kuala Lumpur (Malaysia) who said he felt that his correspondent was in the next room. The sound is clear and natural. The correction of background noise is excellent.
The look: I already have several Logitech Pro 9000 webcam but this HD Pro C920 is an aesthetic success. It is very elegant, either on a screen 24 "or hanging on a portable PC.
The software: complete and easy to adjust. No confusing menus or unnecessary.
In short, the Logitech HD Pro Webcam C920 webcam is approaching professional performance costing several hundred dollars (I participate in international videoconferences, so I have a point of comparison.)
This is definitely the best quality / price on Amazon search. Warmly recommended.
