              Till      Hi there,
the knobs of the product (clone) I have received are much harder in comparison to the original Rumble Roller I had used at the osteopath. For that reason I had to return it.

              S.T.      It does the job and is really good for my stretching..

              Bryan Taylor      bought roller for wife's back issues.
large roller with significant studs that took a while to get use to.
sturdy & looks like it will last.
