Hyperice hypersphere massage ball for muscle release

I used this a 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.
