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

Gives the forearms a decent work out.

As a toy it's not worth the price, but it's not a toy: It's a piece of workout equipment. I haven't found anything that works my hands and forearms quite the same way as this funky little orb. I'd say the build quality is about what I hoped for; metal exterior, fairly weighty, and nothing loose/jiggly. The LEDs are bright and more turn on the faster you spin it, making me want to spin it as fast as possible. The wrist strap is also a nice touch (though it's a bit difficult to attach). Overall I really like it and it would make a great gift for any fitness buff.

I purchased the GOZATO Auto-Start Wrist Power Gyro Ball. It is a fantastic tool for strengthening the wrists and forearms. With its auto-start feature, using the gyro ball is incredibly easy and convenient. Give it a quick spin, and it activates, providing resistance that engages the muscles in the wrists and forearms. The gyro ball is compact and portable, making it perfect for use at home, in the office, or even while traveling. It offers adjustable resistance levels, allowing users to gradually increase the difficulty as their strength improves. The gyro ball is not only effective for building wrist and forearm strength, but it also helps improve grip strength and coordination. The smooth spinning motion of the gyro ball creates a fun and engaging exercise experience, making it enjoyable to use and motivating to continue with regular workouts. Overall, the GOZATO Auto-Start Wrist Power Gyro Ball is a highly effective and user-friendly tool for enhancing wrist and forearm strength.

I've had multiple NSD Spinners including the autostart version as well as heavy metallic variants.I'm currently recovering from an elbow injury and trying to strengthen my forearm to help with the recovery.Here is my take as a former NSD Spinner user (can't find the autostart and lost the starting string for the metal version).Build Quality: Compared to the NSD Spinner, this is noticeably subpar specially with the inner componentNoise: This one makes quite a bit of ruckus when you stop rotating it. I don't know if it's due to the component seeming unpolished or this is normal for this particular model. While it's being rotated there is almost no discernible difference between this and the autostart models of NSD Spinner. Smoothness of the metal one was on a different levelFelt weight/resistance: It's a nice medium between an autostart and metal versionI bought this to start and possibly move up to a different model in the future. I think i will hold up and try to refurbish the metal version of spinner that was left neglected for yearsEDIT: Starting to get instances where it can't wind up to start the gyro. Sometime it seems to help when you rotate it manually by hand then reversing it to see if there is felt resistanceEDIT: This thing was making such a ruckus when it get spun up to a decent pace. I went ahead and bought a NSD Spinner. Oh boy what a difference. Skip this garbage and buy the proper spinner. It's a night and day different in the way it spins as well as the lack of noise with NSD spinner. I think i can actually take it to work and spin it in the office without someone from another office across the hall inquiring about it

At first, I thought about returning it because I thought it wasn't working. But once I figured out how it worked, it worked like a charm and I love my Gyro ball! It's fantastic to get my forearms stronger.
