Q: Total piece of junk!! DO NOT BUY. I've spend the last 4 hours trying to install this piece of crap. I've downloaded drivers, uninstalled, reinstalled, searched the internet for solutions...only to find a ton of people with the same issue....CAMERA NOT DETECTED. I should have bought a Logitech. I've learned my lesson. A great waste of $23. I'm glad I didn't pay a dime more for the awful product!! Not worth my time or cost of returning it. Thanks Microsoft!!

A: An incredible WASTE of TIME and MONEY. Next time I'll buy Logitech.
