Although I have the proper wired sensor bar that comes with the Wii, I occasionally take my wii round to friend's houses and use it on other tvs in the house - and this wireless bar is perfect for such occasions. Whilst it is a little hungry on the batteries (I'd suggest buying a few packs of rechargeable batteries) and a bit bigger than I expected, it works perfectly with no problem at all to set up (just press the on button). Apart from the Wii itself and the controllers, this is probably one of the best accessories I have bought and would have no problem recommending it for use as a secondary sensor bar for when you are using your Wii away from the normal tv you use it on if you don't want to have to unplug and reposition the wired sensor bar all the time.
