Cryosphere Cold Massage Roller Ball - Massage Ball for Cold & Heat Relief, Myofascial Release, Trigger Point Therapy, Muscle Knots - Deep Tissue Ice Massager

Excellent for the price and really seem to work, great to use them hot or cold. I am very pleased with this purchase and would definitely recommend.

This massage ball is by far the best quality I’ve bought. Its 60 mm size is perfect. Easy to hold and use I mainly use it hot like the fact you unscrew it I don’t hen place the ball in boiling water 5-7minuet stays warm for while. This is good to use all over as well as using it on others most people I work with find a massage with this beneficial. Highly recommend

Great muscle relief, really easy to use and comfortable to hold. Roller action really smooth and worked a treat on my tight shoulders also Loving the fact that it can be used hot or cold.

Great item. Just what I wanted

I had problems with my elbows and knee and this is worked really well. It very easy to use and the coldness last quite a while.

Haven't tried yet

I ordered the newer version with the ABS screw collar. Seems very well made and the top screws/unscrews from the base very easily.The action of the rollerball is good, sometimes sticks a little but I've found this is when rollering over clothing. It is a smoother action when on the skin which I presume is getting some natural oils from the skin which makes it glide easier. Not tried it with any massage oil yet but I imagine this would help, and the beauty about this is its so easy to take apart and clean.I'm yet to try heating or freezing the ball. I imagine this could have an impact on the action due to expansion or contraction but this is the same with any brand of rollerball with this feature.Its a good size, about right in fact. Any bigger and would be too big to handle, any smaller and wouldn't have the same massage effect. It's great for the chest, arms and if you have a willing partner, brilliant for the back muscles. I often use a lacrosse ball but sometimes difficult to position and roll. This is much better.Overall, a little more pricey than others on amazon but I give this the thumbs up.

Im not really fat, but i have a sore muscle deep in my glutes , i came to find trying to roll this on a fatty area of your body your skin can almost get pinched inbetween the ball and the plastic that makes for a really painful shock
