I used to play wiifit a lot! Haven't been able to since we moved house a bunch, but I've just rearranged my lounge to give me more space. I have the Wii version, and I love the rhythm boxing and stepping ones too!! I had a rechargeable battery base, but the plug got squashed, so now I have to use normal batteries
But I always take batteries out of my remotes and such, so they haven't died on me yet!
