Was looking for a high quality cam, because I a lot for work and Skype video calling operate. Got the C930 ordered and am very happy with the result - the installation went by itself (Windows 7) and the difference in quality to my old webcam (Logitech C525) is enormous. I'm very satisfied and would recommend the webcam for all people who are looking for the highest possible quality. PS: Sound quality I could not check, since I use an external microphone, but I'm assuming that this is satisfactory.
