Some comments about the NSD Powerball
Powerballs - they rock !! We bought a Powerball for all the guys in the office to use, and soon we had setup a web-page with all our names on it and the highest scores. Great fun for the office - http://www.hashbang.org.uk/powerball/ It was really easy to get one from the powerballs website and I had my new powerball at my door in 2 days. I showed it to friends and family and they were amazed at the speed that this little thing gets. (My family also had a try - Dad, Mom and Granny!) I have since achieved the 4th highest score in the world and am very proud of my purchase and my score. A powerball is just one of those things you have own! ...Steve Ouzman, United Kingdom
I'm very pleased with this little wonder. already got up to 10220 RPM's, now comes the slow path of building up strength to powerball even faster. after a month of use of the powerball I noticed how everything in my hands feels lighter than before. not to mention the fun I have with it by building up a strong arm and annoying my friends with the spinning noise :) ...Matthias Vandegaer, Belgium

Some comments about RPM Sports
Simply put - that is the best customer service response I've received and experienced in years ...Andrew Gingher, United States
RPM sports are as friendly and obliging as the web site suggests. ...Bob Harris, United Kingdom
My god, every time I read some correspondence from you it just blows my little mind how awesome your customer service is! Iíll keep it quiet, but you have no idea how much I appreciate that. Wow, your company is unbelievable! Iíll be showing it off to all my gadget obsessed friends who will no doubt be overcome with jealousy and Iíll instruct them to purchase their own from you. But seriously, feel free to charge my card another $5 more if you need to cover costs, I donít mind! MANY, MANY thanks! Yours is the way a business should be run - Cameron ...Cameron Adams, Australia
