Self-Starting Wrist Gyro Ball Power Ball Trainer Ball Wrist Strengthening Device Forearm Exerciser Strengthen Arms Fingers Muscles birthday present

Great little gadget works your wrists and arms very well makes my shrimp arms feel good used 3 days so far feeling improved strength in wrists very good product very durable and does a good job I'm very impressed and pleased with this would recommend to anyone starting to do arm work 😀

I bought this and a 'Powerball' at the same time for purpose of comparison. The gyroball is a quarter of the price, but not even a quarter of the quality.Winding it as instructed to start it, it is really easy to overwind, and mine now has a little piece rattling around inside it. Before it broke (within 10 minutes of getting it out of the box), there was very little resistance when you circled the wrist, no sense of a workout at all. Don't buy this. Buy a Powerball, which works your wrist and forearm muscles hard. (No affiliation!!)

Defiantly gives your wrist and forearms a workout once you get the hang of it.

This is a great workout. So, I bought another one, so I can practice spinning both at the same time. Man, what a great workout in a couple of minutes. Highly recommend. Yes, you can spin up 2, it is not that hard. If I can, anyone can.

Broke in under 6 months. Normal use, wind back doesn't work so now just a paper weight.

The exercise in to helpnstrenth my wrist helps

It works. i can see the difference

Excellent and easy to get started works as intended
