Auto-Start Wrist Power Gyro Ball with LED Lights, Wrist Strengthener and Forearm Exerciser for Stronger Arm Fingers and Muscle

This gyro ball is very easy to start, which I love. It’s the perfect way to finish off an upper body workout—just a minute or so of spinning gives my forearms a great final burn. The LED lights make it fun to use, too. ​One thing to note: It can get quite noisy as the speed increases. It's not a silent device, but if you don't mind the sound, it's a fantastic tool for a quick muscle pump at the end of your routine!

Works great! Self startup works every-time, no need for a pull string like others.

As far as I can tell, it's broken. I can't get it to work, straight out of the box. It doesn't "wind" in the way that it should, and when it does, it doesn't hold the rotation. I'll probably return it.

When I first unboxed the ball, it worked perfectly. I got the concept and it was really nice. Worked my wrists and arms. Unfortunately it broke after about 5 minutes. In discussing with others and looking at reviews, it seems there are a quite a few ways in which the ball can be broken. I guess if a person were to strictly follow all the advice from the maker, perhaps it would not break. I guess I broke it after I set it down on my desk with it still running (phone was ringing...). I will not re-order because it's apparently too easy to break it. 06-21-2022 - Addendum. I tried it again the next day and it worked fine. So I am thinking either I was doing something wrong (works every time now, however) or something that was not functioning is now ok. In any case, it works good so far. Hopefully will hold up in long time usage.

I chose the "Colourful Light-Transparent" option because it comes with a zippered case and a gift box. It’s an excellent gyroscopic ball, nicely weighted but not too heavy, runs smoothly with a satisfying hum. It’s better than the less expensive ball I bought for myself marketed under another brand name, they all look alike right? I was content with that one until I tried the Gyro Ball I bought to give to a friend - it’s noticeably superior for just a couple dollars more! There’s a learning curve with any of these balls, be patient, watch video tutorials, don’t try to match the speed you see on YouTube. I never use the strap because I like to switch hands. The case is great to keep the ball and it’s internal moving parts, dust-free. The gift box is simple but attractive.

Works great

This is an excellent product. I bought two of them and so far I’ve had no issues. It took a day to develop the sensitivity needed to keep the unit rotating. Once spinning it only takes a little bit more effort to really get it spinning and it becomes one tough cookie to hold on to. Keep in mind this is NOT a perpetual motion machine. If you stop spinning the gyroscopic ball with your finger/wrist/arms it will slow down and stop fairly quickly. It is tricky to get the feel of it however in time you will be doing circle variations, counter circles, figure 8’s, and finger tip rotations. If you hold it with the internal ball upwards it will slow down a lot faster so KEEP THE BALL OPENING DOWN. A common complaint in reviews is that the wind up gyro starter doesn’t work or breaks. Both of mine have worked just fine. I am assuming that most of the people who have had issues with the wind up starter A.) did not read the instruction paper, B.) failed to hold the ball in place when winding it up, and/or C.) excessively over rotated the starter beyond it’s stopping point. I expect a little common sense would go a long way in resolving these issues. I am very happy with the purchase and have convinced several other people to buy one. The unit has a quality build and I highly recommend it.

This did help my wrists while it worked. Its an odd device, and it took me a minute to understand how to really use it, but once I did it provided some relief for some wrist pain and irritation I have. However, it has pretty much stopped working in less than a week. I'm not rating it lower because I'm really not sure if I caused the failure. You start the device by essentially winding up part of it, and I think I may have overwound it. It's also possible that I was using it too quickly and causing strain. But, for whatever reason, it no longer works :(

Great tool for exercising the tendons connected with tennis elbow. The faster you rotate the wrist the more you resistance you get and better the exercise. ( Just need to jump start it once before every session using your thumbs, the instructions are given in the box and are very easy to understand) As a tennis and badminton player myself I will recommend this to everyone who plays these sports regularly. Fantastic product!

Effective and does what it says. Great value at low price. The LED lights make it slightly childish but its alright.

Muy padre, espero usarla mucho

Works great! I like the added lights, makes it more fun to use. Got it on sale for $23.99 compared to the other models that sell at $34+. I'd recommend it! Gives my hand (wrist, fingers) a great workout! Easy to use too!

works as expected, quality is good, achieves high RPMs easily and provides good resistance.
