Wrist Ball, Gyro Power Self-Starting Mute Centrifugal For Finger Grip Force Arm Strength Trainer, To Relieve Stress, Platinum Gold, With Colored Lights And Rope, 270G

It's true what they say in some of the YT reviews I've seen. This Gyro Ball works not only to strengthen your arms, but a good exercise as well for those working at the office sitting almost all day in front of their PCs.

No matter how you try to keep it running it stops. It's just bad quality I guess. Ordered the original Powerball after day and night difference

Probably the most interesting product I bought on Amazon. It’s based on an ingenious idea and physics behind it just simply amazing. Need to get a hang of it first, but once you overcome the learning curve, it’s a lot of fun and good way to activate arm ligaments while sitting on the desk.

You need to move the wheel until it tight then release it and start shacking your hand to increase the speed of the power ball.

I'm using it for a while now and still in perfect condition and as expected

Doesn’t work well and consistently

Overall good product, feels a bit cheap but that's what you paid for, and the box was damaged and it's not a shipping damage because it's well protected probably damaged from the seller side.

Really good product and works well.
