My grip strength has noticeably improved after a week of daily use, and the way it works the forearm from every angle is surprisingly thorough. I’ve been using it during work breaks to ease the tightness in my wrists, and it’s already helping with the early signs of tendonitis.

I was skeptical about the gyroscopic mechanism, but after a few minutes the spinning motion really engaged my forearm muscles in a way I hadn't felt before. It's already helping with the stiffness from typing all day.

After three weeks of daily use, my wrist pain from typing all day has noticeably decreased, and I love how the gyroscopic resistance forces my forearm to work in every direction. The smooth, continuous spinning motion is oddly satisfying and really gets the blood flowing.
