  • they r so cool lol i used my friends and by fluke i got it started withouth the pullcord i used my thimb and i found out that when its going a descent speed move ur wrist slower and it picks up speed

  • I HAVE TO GET ONE OF THESE!!

  • what it do?

  • can someone tell me where to get one of these? i messed with my friends today but he got his in germany he said.

  • I got mine today Ive been doing it all day lol its addicting i use it for boxing

  • damn, there's some stupid people making comments. Why don't you guys Google the name and find out what it's for?

  • as the speed of rotation increases so does the apparent mass because of gyroscopic force, so it "feels" heavier and works your muscles.

    If you can get the dang thing spinning. Good luck. I can't (yet).

  • I finally got it going without the string.

  • I FINALLY got it to spin without the string (thumb flick) and then could accelerate it with wrist motion. I had a crappy one at first, that was my problem, and then bought a real one. Good equipment makes a difference. It's really fun! My NSD Powerball rocks! It has flashing lights on the spinning part that blink every time they pass the hole where you flick your thumb to start it, the lights give the RPM. Cool toy! I'm in my 50's, but I still love cool gadgets as much as I did when I was 5.
