Review on 🔵 GeToo Cryosphere Cold Massage Roller Ball - 2.8 Inches Cryosphere Cold Roller for Deep Tissue Massage, 6 Hour Cold Therapy, Detachable Rolling Ball - Blue and Black by Negil Dunnigan

I have trouble using it on my shoulders and back (female, 55). This size will look great on the back. I think a small size would be better for my shoulders. I used it with relief on my forearms. It's on the cold side, of course. The heating option on this ball is great for sore muscles. I've boiled and heated the water, but good high heat doesn't last long, so I must be doing something wrong with this method. I am very sorry that I bought such a large and difficult one for my hand.
