Hyperice hypersphere massage ball shops for muscle release

Product Name: Hyperice hypersphere massage ball shops for muscle release
I used this a shops few times last year when purchased. Was in the closet and I hear a loose screw inside. When I charged and turned on the ball makes more vibration noise than before. The ball is still 100% functional. I used this ball at the gym on the foam stretch mat. You need that to press into bc on w wood floor it will be too hard and move too much. Let me know if you have any questions.
