If you have a Wii Fit game with the balance board, it's good to keep the balance board in something safe while you carry it around or store it. This sleeve does a reasonable job.
In essence this is a neoprene sleeve that is just fitted to the size of the balance board, with carrying handles on the top end. You have to jam the board a little bit to get it to fit into the sleeve, but once it's in there, it's secure.
The sleeve isn't incredibly thick - you don't want to be dropping your board down a flight of concrete stairs. Still, it does provide some safety against dings or gentle hits while you are carrying the unit around. And since the actual board doesn't have handles on it, just the fact that you have a pair of handles here is a nice feature.
The sleeve is reversible so you have two color options. I'm not really that picky about what color my balance board's carried in, but if you care, you have the choice!
Are there down sides? Well, as mentioned the sleeve is fairly tight. It can be a bit of an effort to shove the board into the sleeve. That then means that I don't tend to keep the board in the sleeve when it's sitting around, because I'd rather be able to just grab the board to use it vs to tug it out of the sleeve.
Also, because of the nature of neoprene, when you pick up the handles, they "sag". There isn't any sort of a sturdy frame to the sleeve, so the whole sleeve pulls and stretches from the handles. I think they could have done better by making a plastic frame of some sort so that the handles were more sturdy at holding the unit in place.
Still relatively minor complaints for an item that does its job quite nicely. If you've got a balance board and tend to move it from place to place, you definitely want *something* to carry it in. This is a great choice!
