DO NOT BUY THIS I repeat DO NOT BUY THIS. Does not hold a charge. Garbage. You'd think Logitech would've fixed this by now its been out for a while. Like a friend told me thats probably why you can't buy it in stores anymore. I wish amazon would let you put no stars, actually this deserves a -20 rating
