I just got home with my new Magic Mouse (AND LOVING IT) but I suspect that device I brought home is an open box item. 1. When I paired the device with my Mac, it says "Reneaz's Mouse" is connected. My name is not Reneaz. 2. The black plastic bits on the bottom of the device are already scratched and worn. 3. It came with Energizer batteries (Is this typical?). Should (or can) I request an exchange? If the item was returned, I do not want to take any changes that the device is faulty.
