Very good product
I just want to start out by stating this is not a negative review.  This product works as intended but the little bumps hurst after a while.  Especially using near the spine and should where the bone are exposed.  This product works very well around the legs and thighs.<br /><br />Technical review, the bar is a solid steel with ball bearing between the bar and the peanut shape massage unit.  The unit rolls very smooth with a good grip.<br /><br />All that being said, if the manufacturer decided to make a variant with out the bumps, I would buy it too.
