I first thought the idea of a wireless sensor bar for the wii would be a good thing. However now I have a wireless one, I've changes my mind, for starters it doesn't really matter too much is it has wires on it as, in my case, the wires just go round the back of the TV anyway, so was really a solution to a problem that doesn't exist for me.

Since this is a wireless sensor bar it needs to get its power source from somewhere else that isn't the mains plug, so it require batteries, and a lot of them, this sensor bar requires 6 AA batteries. So it can be very expensive if you have to keep buying new packs of batteries, so if you do plan on getting a wireless one I would recommend getting a battery charger that you can charge from the mains. Also most battery charger sets only charge 4 at a time so you will have to invest to 2 packs to have enough for the sensor bar to work.

Although once you have brought the battery chargers there aren't really any extra costs, it is still annoying having to charge up the batteries every time they run out, and they can take a while to charge up. And with the wii remote needing batteries as well, there are just too many batteries having the juice sucked out of them. Although unlike the wii remote it doesn't have a bar telling you how much battery it has left in it so you can tell when it will need charging soon. That means it is more likely to run out and stop working during the middle of a game. The only way to really solve this is making sure you charge them early before they run out, which means doing so more often.

Another problem with it using batteries is that it is much thicker and blockier, and overall less attractive to look at. I used to have the old official nintendo sensor bar on top of my telly even when I wasn't using it, as it was to thin and sat well on the telly. With this one however I don't like to keep it on there as it doesn't match with the telly as well, although at least being wireless it is easy to move out of the way, and you don't have to tie up all the cables.

In terms of responsiveness it seems good, and I don't think there is a difference between this one and the official one. However when it is starting to run out of batteries it becomes inconsistent and laggy, although it could be said this is a good thing, as if you can manage to control the sensor then it may give you enough time to save your game before it runs out completely.

Overall I wouldn't recommend this wireless sensor bar, as the benefits of wireless for something like this aren't worth the negatives, and the positives aren't that great anyway. Batteries really just mean you are solving one problem (which isn't really much of a problem in the first place), by replacing it with a bigger one. Not worth it in my opinion.
