Review on Portable SubZero Cryosphere Cold Massage Therapy Ball for Pain Relief, Inflammation, Sprain, Spasm, Stiffness - Black Gray Ice Roller Ball with Zero Mess Ice Cup by Tricia Pence

I really like this roller. I've used it both cold and warm to relieve pain from a cleft shin. I wish I had had this knee surgery 4 years ago because it is a great addition to my at home recovery plan. Massaging the shin is a bit of a shame, but this roller is comfortable to hold. I've even used it to untie knots in my back. It's strong and well made. I recommend it if you need a little more muscle roll. Note: I've seen many reports of cold or heat injuries. Just use your head. I left this in the freezer to freeze and never damaged my skin cells. As we've all read in the past, you shouldn't apply ice for long periods of time. Here's the same concept, I ride for 30 seconds, then stop for 15 seconds and just repeat the process. Even if you don't put it in boiling water for a long time, it won't burn. I really wonder if some of the reviews are paid naysayers. It's not rocket science, it's just a video.
