Very cool grip exercise. Took me a while to figure out (you have to rotate your wrist pretty hard at the start), but very good workout. Pretty easy to use once you get it started. It also makes a cool motor sounding noise and lights up lol. Would get again for the simplicity and effectiveness of endurance training.

I really wanted this to be the tool that helped me rebuild strength after my broken wrist. I wasn’t even using it every day, so I never imagined it would fall apart in just nine days. My physical therapist had shown me a similar style of exerciser, and when I found this one in an extra‑small size that actually fit my hands, I thought I’d lucked out. For the first week it worked smoothly and felt promising. Then on day nine, while simply trying to increase resistance, it snapped. No rough use, no over‑tightening — it just broke. I’m incredibly disappointed, especially because my wrists genuinely need reliable support right now.

This turned out to be a good purchase but only after a few tries and misses. Once I practiced and watched a few YouTube videos on the technique, it was really easy to use. I used this hand exerciser to strengthen my hands, wrists and forearms. After a few days, I really noticed a difference with strength and flexibility. Definitely recommend.

The ball itself is very high quality and sturdy. I found it a little tough to get going, but I found that "winding it up" by pulling it back quickly on a hard surface, like a wind-up toy car, would get it going well. It is amazing how much "burn" you feel in your hands and forearms. After a couple weeks of continuous use, I can feel my hands getting stronger for sure. The forearms are strengthening a little more slowly, but it seems like its working. It is far more entertaining that I would have imagined! You find yourself fidgeting with it for a while, and getting exercise at the same time. Definitely a good addition to any workout.

A couple of minutes a day and my wrists are feeling better. The built in starter is a nice feature. Every now and then it doesn't catch but a swear word or two seems to fix it. The one I had 40 years ago had a plastic ribbon that I had to keep track of and wind up on the rotor as a rip cord starter. This new method is much easier. The wrist loop is a nice feature too. It can get a little difficult to keep my grip on the ball after a workout and the strap gives me some peace of mind in case I drop it. I saw some reviewers mention that it was hard to start or wasn't working for them but this hasn't been the case for me; mine is working great. The motion is gentle and slow, like swirling an ice cube in a glass that you're holding from the top. As the rotor picks up speed I just have to grip the ball tighter and tighter, I don't have to spin it faster. That said, it did take a bit more practice with my non- dominant hand, but just a bit. Slow and easy. It's a nice way to relax with a light show as a bonus. Like a fidget spinner but with strength benefits. I'm loving mine.

This makes my wrist stronger & more flexible. Thank you!

Most of the time The wind up doesn’t work correctly, it just spins freely instead of winding up tension. When it does wind up, it works fine, and had zero issues getting it going the first try right handed ( dominant hand ). Left handed takes a little effort getting it going fast, but have only had it a few days, and only tried left hand twice. Within 2 minutes my forearm is burning, but that’s the point. I’m disappointed that the wind up mechanism doesn’t work correctly, and I thought it was supposed to change colors according to the speed, but it is multicolored the entire time it’s spinning.

I was under the impression that as long as you are rotating your wrist, it would keep moving but this thing stops after like 10-15 seconds. Something is telling me that isn't right. if this is normal im sending it back because the constant stopping to "reset" it is annoying.

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..

Satisfied with the product, it’s exactly what they described

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

This item does not work as expected.

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