It's the second time I own a powerball, I think they are awesome for training your wrist, fingers and forearm strength, of course depending on how fast you're spinning it. I also noticed they effectively lower stress, kind of like a squishy ball on steroids
Is anybody else using one? I was thinking about whether the vibrations it is causing in the arm could be in any way damaging. At high speeds I can even feel my shoulder vibrating.
Here is a video demonstrating how it works

And a guy hitting 22000 rpms which is insane
