Digital camera reviews of Dynaflex Powerball With Speedometer
Digital camera Review: Use wisely
Summary: 4 Stars
I liked it a lot.
In the beggining, it took me some time to realize how to start and hold it, but afterwards i just kept using it over and over.
I was once upset with the difficulty to start it and all the noises that it made, so decided to put in some wd-40 to soften its roll... bad idea, it went too loose. So i've openned it (it's easy to) and dryed it all. Now it works better, but doesn't get all the rpms it used to.
And after using it so hardly i have hurt my wrist. Now can only use it with my left arm, until the right one gets healthy again.
Well, i recommend its use, but wisely ;-)
