XMALL Wrist Power Gyro Ball Hand Forearm Strengthener Wrist Trainer Auto Start Colorful Lighting (Black)

Recebi o produto no prazo estipulado pela Amazon. O produto é de excelente qualidade e funciona perfeitamente. Porém a embalagem é diferente e não veio case. Mas por ser bom resolvi aceitar mesmo assim para evitar aborrecimento..

Once you get it, you've got it. Addictive.

I returned it. It didn't work for very long once activated; have to frequently re-activate. A stress ball might be adequate.

74yo female with mild hand arthritis and desire to increase hand strength> This was awesome for the great price of $14. It was easier to wind up than the other brand I bought for more, and it also wants to gyro much more easily so I can get it into the mojo pretty easily. Its fun for a hand and forearm workout. This one without the RPM counter is fine because I am more concerned about how long it goes in a smoothe gyro run than about anything else. I like the way the lights flash when I have it going right. It weighs slightly less than the other which is good.

Works properly
