A great virus protector may protect you from having a privacy breech in your webcam, but that does not mean you should not buy this product for your C920 to be safe

I can't think of what you might think would go wrong with it, but... it has never fallen off of my camera (a Logitech C920), even with me moving the camera around from time to time

Got a Logitech C920 (nice pretty camera) with an ugly, scratched privacy shutter on it.
