Some comments about the NSD Powerball
I've been using my powerball for about half and hour a day for the last 2 weeks and can already see a big difference in my forearms as they are now much bigger and more muscular. I look forward to seeing how much distance it will add to my golf drive. ...Adam Boyd-Brown, United Kingdom
This has got to be the coolest gadget around. I got it to relieve my carpal tunnel symptoms and it really does work. I no longer have those nagging pains which is great. An added side benefit is when my teenage boys decide to roughhouse with the 'old man' I can latch on with a "death" grip and hold my own. ...Bruce McLean, United States
I am very pleased with your product and service - I received professional and courteous service from your company, and follow-up e-mails to verify I had received the powerball. I received the powerball within 5 days of the time I ordered, which in truth, was much faster than I had expected. I am also extremely pleased with the results, as I can attest that I have seen a significant increase in the strength in my wrists and forearms. In my golf game, I have not only increased my distances with each club, but I am able swing with a smoother rythym. I don't feel I need to swing as hard to maintain the same distance, which has helped improve my accuracy. Plus, I only need to use the powerball for approximately 10 to 15 minutes daily to achieve good results. Thanks Again. ...Larry Smith, United States
I got it for last christmas and had some problems at first, I couldn't get it spinning. I thought it might be faulty, but it turned out my technique was just bad. :) Now my record is 11.706 (with a Neon Blue ball), I'm always improving and can feel my arms getting stronger. I can't wait for the summer to see what it has done for my golf game. ...Johann Bjarkason, Iceland
It is a truly addictive item which I use every day and it has improved my grip strength a lot even in daily situations like opening a jar of pickles or unscrewing an old screw. I like it a lot ...Arturas Lazejevas, Lithuania
