Pros: Awesome when its new...

Cons: I have now purchased two of these mice. The things seem to break down rapidly after about 6 months of use. The little lcd screen stops working altogether. The paint bubbles up and wears off which is worries me a bit, is the paint noncaustic? Also the left mouse button breaks, when clicking you get random dbl clicks or it will unclick while the button is pressed and held. Also you have to reinstall the software if you change usb ports which is annoying as well.

Overall Review: If you do get one of these make sure you have a backup mouse in about 6 months or so!
