With this new wireless Wii sensor bar you get the benefit of a wireless sensor bar, but if you wind up leaving it setting on top of your TV anyways, it has a secondary useful function, telling time. This way you can tell how much of your life you wasted playing your Wii.
It takes 4xAA batteries and has a blue backlit LED clock in the center of the sensor bar. It does look somewhat bulky as far as wireless sensor bars go though.
I myself just got a Wii and I’ll be needing one of these soon so I can take my Wii places since I adhered the included sensor bar to the top of my TV. If you want one, it will cost you $18, not a bad price as Wii accessories go.
