Some comments about the NSD Powerball
I received the powerballs and made the mistake of opening them at work. After a short while I was able to key in on making the gyro spin in one direction and I got that baby humming to about 8000 rpms or so. (My right arm feels swollen and I can barely type this letter). This is one of the coolest gadgets I've ever seen. I should be able to rip doors off their hinges in just a short while of using this. What a workout!!!!! Thanks!

Just wanted to thank you for sending it with priority post! The powerball has just arrived yesterday and i just can't let it down! My current record is 10202, but i'm only 16! With time i'll get better! My arms are exausted! The powerball is fantastic! Such a little innocent looking ball, but spin it (and spin it fast!) and the innocent look just fades away! Yours Sincerely Pedro SebastiŅo @ Portugal ...Pedro Sebastiao, Portugal
Just got my Powerball today, and my word! I've barely put it down; I'm even using it now as I type this statement. Managed 10,415 rpm thus far and it feels like it really is actually building the muscle in my forearm (judging by the burning sensation) and its just superb fun too. Even my mum thinks it's mint. A winner all round (no pun intended. Well done Powerball ...Toby Lunn, United Kingdom
Just got the powerball yesterday, got it straight out of the box, and got to a pathetic 8400 rpm. Been workin on it all day yesterday and today and now up to 10337 rpm. Such an addictive gadget. Keep up the good work, James ...James Ford, United Kingdom
I'm a bassplayer and need a good warmup because i have very cold hands, and that's exactly what this thing does !!! ...Sven Beckers, Belgium

First of all, let me tell you how GREAT the RPM sports staff are. On the shopping page, it said the ball should arrive at about 6-8 days. Well it arrived in 4!! FOUR DAYS!! ...Andrew So, United States
