If you’ve been using the Wii balance board in Wii Fit then your white balance board is probably not so white anymore. Once company, Linx products is hoping to fix that with protective covers for the boards.
The protective covers are the same ivory that the board is traditionally and can be washed up to fifty times before they need to be traded in for something new. The covers also feature an anti-bacterial agent to keep your board disease as well as dirt free.
A protective cover would certainly increase the life of your balance board, or at least increase the amount of time it doesn't look gross.
Right now the covers are only available in Japan for around $14. look for a knock off elsewhere soon.
