“BOMU-W24A/BL mouse” may not roll off the tongue as easily as “Wii Remote”, but they do have something in common. Both are operated by waving them about in the air (remove all nearby breakable objects before use – including Grandma!). The mouse’s optical sensor also allows it to be used on a desktop or other flat surface. For use in the air, a gyro sensor is utilized. Perfect for multiple tasks such as general computing, gaming and presentations. Operates up to 10 meters from your pc. Up to 96 hours use from a nine hour charge. Great mouse. Shame about the name!
