If you like to hook your Nintendo Wii at different locations and/or want one less cable floating around behind your TV, the wireless Wii sensor bar is definitely something to check out. The wireless sensor bar functions the same way your normal Wii sensor bar would, except it runs on a 9V battery. This isn’t too much of a bad thing, you’d just have to make sure your Wii isn’t left on when you aren’t around. The wireless sensor bar site doesn’t exactly say how far the sensor bar can be from the Wii, but chances are, you aren’t going to place the bar too far away from your console. The only question is, does it come in black?
