I have a  C920 bought a few years ago.  Camera is very good in most situations. 
 One problem I found is that it is prone to interference from flourescent 
lights which causes moving shadow bars across the image.  These are just a bit 
distracting.

A also have a more recent Logitech C615 which was cheaper and appears to 
perform as well as the C920 - even down to the bars from flourescent light 
interfernce.

Both are very good when used in different light conditions (dull to bright).   
I do not use the Logitech inbuilt microphones.

Cheers
Alan
