Hey guys just wondering if you had the cahnce to see this thing called a 'powerball'?

"Bring your new Powerball up...up to 10,000rpm...the forces are now much stronger, much more vibrant. Higher! Take it to 12,000rpm...no, higher still...take it right up, thrashing and jerking as your arm and wrist try to control and calm it down, faster and faster it spins until you have it up to an unbelievable 15,000rpm at which point it's exerting almost 40lbs of pressure on your limbs and is traveling at nearly 250 revolutions per second - no batteries, no motor, just pure gyroscopic power - the fastest human propelled device ever created!"

They seem quite interesting...I want to get one! What are your thoughts on them?

I had one for a while. It was pretty good for developing grip strength (much better than those spring grips), but it wasn't anything terribly special.

The marketing pretty annoying to read on that board.
"You've just bought the most effective tool for martial arts! Now have a black belt too!"

I used one not too long ago for physio for my wrist.
Couldn't really get it to work...but the physiotherapist did....

I suck. :(

"It was pretty good for developing grip strength (much better than those spring grips), but it wasn't anything terribly special."
I agree with that, those spring grip thingies are fairly linear in their muscle recruitment.

Ah cool. Haha. Yeah the marketing is a little over done....least it didnt proclaim to make you a leathal weapon...yet.

Ender how high did you get the rpm up to? They have a competition as well...seems interesting :). But increased grip strength is always good...how bout wrsits and forearms?

i don't know about the RPMs, but if you really yanked the string for a minute or two you could get some heavy-duty vibrations. Definitely works for the wrists and forearms. I think a lot of tennis players use it as well.

I had one a while back (it eventually got stolen). You can definitely feel the burn in your forearms, but I can't say if it increased my grip strength any. Still, it was something to do while I was doing my homework.
