## Description

Review: Great product! - I was very skeptical at first, but I am now a believer! Once you learn the proper technique, which only takes a few practice times, you feel it working and strengthening your grip, wrist and forearms. I use for a few minutes in each hand and I know this will improve my strength. I’ve read reviews stating the gyroscope knocks against the housing, but I feel that is normal as the direction of the gyroscope does change with slower hand movements. I feel this is sturdy and a good value for the price.
Review: Don’t waste your money - Don’t waste your money First one I bought I sent back due it doesn’t move around inside the ball. Replacement barely moves.

Don’t waste your money First one I bought I sent back due it doesn’t move around inside the ball. Replacement barely moves.

### ⭐⭐⭐⭐⭐ Worth the buy
*by J***D on July 12, 2025*

I enjoy using this product to loosen up my wrists and forearms. It is easy to start, but you have to get used to the motion. Once you have the motion down, the benefits of using it are great!
