I'll have to check it out. When I saw this, I was thinking of PowerBall, the gambling, haha. Some guy just won half of a $370 million jackpot on another lotto game.
Have fun with it. It's not a perfect companion though, because even for 1h cubing, because you don't really use your forearms. It's great for drumming though.
It's lots of fun though. However.. some advice. NEVER.. NEVER STOP THE POWERBALL with your NIPPLE. I was lying in bed last night, it was spinning at probably 7000-8000 Rpms... when I decided to graze it against my chest. Well, my nipple was unfortunate enough to get shot up into the ball, and it gave me a nasty friction burn. It hurts. Awful terrible idea.
