This is a great price for this wee machine! Personally, I don't get them?!? My brother produced one at a party, and everyone was competing to see who was the best. For some strange and unfathomable readon, it seemed the boys were better at this than the girls..... (!)
This is a low, low price @ play.com, but will probably go fast, so get it while you can.
Details: Designed to improve the wrist muscles, simply set the inner section spinning, rhythmic circular hand and wrist movements not only maintain the rotation, but also make it steadily faster. Increased in centrifugal forces make it harder to keep hold adding resistance to your wrist thus making you stronger. Not only is this a great exercise for your wrist, it is also extremely addictive as it incorporates a high score system.
The perfect instrument to gently rehabilitate lower forearm and wrist joints affected by carpal tunnel syndrome, repetitive strain injury, arthritis & previous breakage.
