Review on Vive Massage Ball Set (4 Piece) - Ultimate Foot Pain Hot/Cold Therapy Kit for Plantar Fasciitis, Heel Spur, Sore Muscles - Trigger Point Relief, Full Body Circulation Roller - PT Spike Massager by Beverly Smith

This set offers great value for money as it includes a castor and ball set. A caster and a black ball are the only perks. Two spiked balls are almost useless, they are SO hard, when I try to twist my leg it just rolls on the wooden floor. Some disappointment that only half seems useful to me. A much cheaper option than buying the caster separately but I almost wish I had just spent the money instead of having a set of balls that are even useless.
