Saved my career,
Verified Purchase(What is this?)
This review is from: Powerball Neon White Pro Signature (Sports)
I bought this last year when suffering from RSI/tendonitis in my left arm; I am a viola player in a professional orchestra and for 6 months prior to using a powerball my forearm in particular constantly ached and felt tired. It throbbed from the moment I woke up to going to sleep.
I tried sports massage, stretches and ibuprofen cooling gel, all of which helped a little but never sorted the problem. Then I saw the powerball on Amazon and thought I'd give it a shot; it seemed relatively inexpensive for the testimonials it was getting.
I noticed a difference the day after I started using it. When I woke up my arm felt fine, and within just a few days all symptoms which had been there for months disappeared. After over a year I still use it regularly and have had no problems since. I swear by it.
This model is great, I love the lights. My advice is not to buy the Screamer model unless you want to annoy all those around you. This isn't silent but the screamer will aggravate your tinnitus once you get it going!
