Bought it refurbed. for $20 on eBay (w/o shipping), and this is a $75 mouse
At least on Logitech's website. Anyway, I like the buttons that are found on this mouse. There is mute, volume up/down, IM (with notification light), email (with light), and back/forward keys. With all of these buttons (all of them work well BTW), this mouse feels well in my hand. Not too big, nor small. Considering the price I paid for this mouse I would say I got a great deal, and it came in like new shape (actually, I can't find anything preventing it from being new besides the packaging). If your thinking about buying this mouse, and wanted to ask something, go ahead
