Review on Massage Ball Hot Cold Roller Ball - Relieve Muscle Pain Fast - Stainless Steel Gel Balls For Heat Or Ice Therapy-Feet Pain-Plantar Fasciitis-Back Ache-Myofascial Release–Deep Tissue Trigger Points by Todd Raynie

A surprisingly great product for neck, back, arm and footpain, particularly neck and plantar fascitis. Works so well, we bought two and gave one to my son who has plantar problems.Well made and quite easy to use. You will likely never use it for hot therapy, as it works so well cold.Put it in the freezer first coupla times, only to learn the ideal way to use it is to store it in the fridge door, as it gets too cold in the freezer.Holds the cold for a long time, so you can freeze it, and take it with you for a car trip.
