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

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

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

Pros: ✅ Auto-Start Mechanism – No need for strings to get it going. Just wind it up, release, and it starts spinning smoothly. ✅ Great for Forearm & Grip Strength – After just a few minutes of use, you can feel the burn in your wrists and forearms. ✅ Compact & Portable – Easy to carry around, making it a convenient workout tool anywhere. ✅ Durable Build – Feels solid and well-made, with a smooth spinning motion. ✅ Fun to Use – It’s almost like a fidget toy but with real fitness benefits. Cons: ❌ Learning Curve – It takes a few tries to get the motion right, especially for beginners. ❌ Lack of Resistance Control – The intensity is based on how fast you spin it, but some might prefer adjustable resistance. ❌ No Digital Counter – Unlike some high-end models, this one doesn’t track revolutions or speed.

Es un excelente producto, de muy buena calidad, especialmente para ejercitar el antebrazo, la muñeca, los dedos, en sí, un gran aliado para terapia y relajación.. 100 % recomendado.

Muy buena para ejercitar el antebrazo

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.
