Review on 🔵 CFF Dual Massage & Mobility Ball - Ideal for Recovery, Trigger Points, myofacial Pain, feet, Hands, hamstrings, Back - Deep Tissue Hot /Cold Massage by Marshall Dickinson

I have used this remedy for buttock/piriformis pain and have found it extremely helpful. I'm surprised by the negative reviews. I have several individual bullets of different sizes and another of the same alloy but much softer. It's a lot more useful than the softer one, but the reviews I see are about the same for both. The only downside is that the diameter is a little small for rolling the lower limb on the floor, but easy to use on a chair. I've also used it to ride the thigh above the knee joint. I bought a second one.
