This is the 2nd time I tried to buy this mouse. The first one didn't come with a battery, as advertised, the box looked used, and the picture on the box didn't even match the mouse advertised. And...The instructions (not that you really need any - but still) weren't even in English. I had wanted to give it to someone as a gift, but would have been embarrassed because of all things mentioned above. So I returned it. I waited 3 months, and thought I'd try again...hoping for different results. NOT... Same exact product, same exact complaint verbatim. I guess - What did I really expect, Right?
