Customer reviewsFirst impression German engineering
I bought one of these from Sharper Image many years ago. It was a polymer type that lasted for, I m guessing, a hundred s of hours of use, unheard of in this day age. I simply wore it out Literally threw it away a year ago or so This one looks cool, sounds cool and works as advertised. Great for strengthening handgrip, wrists and forearms.
