I do not recommend buying this mouse. It was a great deal, but after only a couple months it no longer holds a charge. The cradle doesn't connect well to the mouse, so it hardly ever charges. I also use regular batteries, and it drains them in what seems like minutes. Also, the buttons are not easily programmable because the mouse software isn't very compatible. I think that the product it just very very low quality. I am now going to have to go pay for a new mouse, and I won't be buying this brand again.
