Massage Roller Ball, Deep Tissue Massager for Myofascial Release, Mobility Ball for Exercise and Workout Recovery, Alleviating Neck, Back, Legs, Foot or Muscle Tension - Blue, 8cm / 3.15in

works great and easy to take with me when I am going places

Love this thing. Works great. A little on the larger side if sitting in a chair but man it works.

I thought it was solid rubber but it’s not. Still serves its purpose but slips easy if your using it against a wall for leg or back

This could be the perfect ball, the yellow portions are great and have some sort of "grip" against walls or the floor, in contrast the black portion is super slippery so you have to be very careful when using this to not slide. Giving it 3 stars because I got these on discount. This could have been the best ball if those black parts weren't so slippery

Does the job at a reasonable price and made well!

Used this for massage after carpal tunnel release surgery and it was very helpful

I bought this for a yoga retreat. It was too hard and the spikes were untenable. NOT suitable for myofascial release IMHO.

Great for sore hips, glutes, and sore back
