Title: Just a toy
Review: If you are looking for some entertainment, then this toy will also help you develop strong forearms. However if you are serious about exercising, then this toy will just frustrate you. It takes too long to get it going (like winding a yoyo) and to keep it going requires some skill. It is too easy to loose the rhythm and then you must restart it. For those that just want to concentrate on exercise this is too frustratingly complex. The only way to start it is with a special little string that is very easy to loose. I purchased this for my kids thinking that they would develop their arms for Little League. They were not strong enough or coordinated enough to keep it going and lost interest very quickly.
Is the review positive or negative?
