NSD Powerball
I bought a NSD 250mhz Amber Powerball
a few days ago and I have been using it since. I have been suffering from pain in my left wrist for the past week or so, and I decided to get one to see if it would help. If you don’t know what they are, it is basically a gyroscope inside of a plastic shell which you rotate around your wrist and it helps to build up muscles and rehabilitate pains. They have been known to help get rid of RSI and other joint pains, and it has been helping so far; after you use it, it really does make you arms and wrists feel rejuvenated. I sometimes suffer from RSI due to the fact I spend so much time on my computer, and is often noticeable after I have been gaming - so I am hoping this should eliminate the problem in the future. And I know you can buy Powerballs with counters too, but with this being my first one, I just want to use it to strengthen my arms/wrists - I can always add a counter in the future if I like.
I got mine for £9.99 from Play.com
, which is a good price compared to some places (free postage too). If you do think about getting one, make sure that you get a NSD Powerball, and not the cheaper copies that are around (as they wont work as well and may even cause more pain than good).
