The bluetooth mouse I bouught a few days ago is a full size desktop mouse for my iMac. When I first set it up it would work about half of the time, but I figured out the problem; it was the NiMH batteries that came with it. They were 750mAH AAA NexCell. Thes batteries mustt have been sitting in th warehouse a long time, they wouldn't hold a charge long, and after a day the charger couln't neven charge them! Because I neeeded a mouse, I sent my dad to a local RadioShack, he bought some of theire brand AAA 750mAH. After installing them, the mouse worked great; it took about 3 1/2 hours to charge them. If you get this bluetooth mouse (or any wireless mouse) buy some good batteries, if you buy rechargable: try to get ones with high mAH (AAA: 800, AA: 2500). If you don't/can't get/use rechargeable batteries, try to get lithium ones.
