I ordered this because I Sensor Bar projected on a wall at 4 meters. Wii being placed behind me, the original cable was too short. This accessory for me was the solution. In addition, the wireless side allows me to move next will I play standing or sitting without risk of a wire and take me to always have the sensor to the proper height. The sensor bar still uses 4 AAA batteries, so think about the rechargeable battery ... With an On / Off button, this saves batteries that must last I think 48 hours of play. No difference between the sensor bar and the original one, except when the batteries become weak, the direction is on.
For a TV, I do not know if this is useful, if not a wire less ... but more batteries ...
