Vibrating Massage Ball 4-Speed High-Intensity Fitness Yoga Massage Roller, Relieving Muscle Tension Pain & Pressure Massaging Balls (Black)

Nice vibration, but it stopped working after just a few uses. I plugged back in and still did not work. Unfortunately I missed the return window by a day. when I dropped it in the trash it lit up, and I found I could get it to work by hitting on the table each time. The seller contacted me and are sending another one, even though I was out of the return window. The ball has strong vibration that reaches deep into the muscles. It is an excellent product offered by a responsible seller.

This is an excellent massage ball for lots of areas! The seller was excellent, shipped earlier than I expected. I then had a question as to how it connected to the charger. The people who sold it, helped me figure that out (it is somewhat counterintuitive!) I could see where it was supposed to go in but there was no opening. But it somehow went in when I pressed the area and it is easy to charge! I am very happy with the overall size and quality of the ball--it is bigger and more effective than another one I have.

It works as it should and appears to be quality. However, l bought it for my hand. I had wrist surgery after a slip and fall. Its a bit too large. Going to try to work with it because its what l need. My Physical therapy office has one ( just smaller) EDIT 2 weeks in it stopped charging. Going to return and try another

It actually works really well

Affordable and useful for self neck massaging. My neck is a bit of a mess and using these helps with the pain.

It works great. Glad my physical therapist recommended it to me

The ball worked great when we first got it. We had a physical therapist help us with how to use it and proper placement. The ball is solidly made so no matter if you're 100lbs or 250lbs, it wont break the outer shell. At about the 2 month mark it started to slow down and last shorter in-between charges till it finally stopped. . I did get a partial refund because the return was after the 30 day period. There should have been a 12 mo warranty, but I could not figure how to get a hold of the manufacturer or sellers to submit a claim. The rest of the reviews looked good, so It may have been a defective one. It would have been nice to have the sellers honor their warranty but all I got was Amazons representatives who seemingly could not help with the warranty claim.

by far my favorite recovery tool. Throw it under the glutes and get all the knots out.
