[11/26/23] The product is well packaged and arrived in visually good condition. I have watched many videos and read the instructions. None of this has helped me. I had a friend that has a competitor product try this. He could not get it to work either. There is a nice card inside the package that asks the buyer to contact the seller if there are issues. However, there is no contact information. Something is missing. Seller, please contact me. Thank you![12/5/23] I have updated the review and the rating. The seller contacted me right away and offered a refund. I very much appreciate this fine gesture on the part of the seller.[1/3/24] My nephew visited me and I was talking to him about the issues I had. He watched some videos and got it to work! Two things that I needed to do differently: (1) I needed to wind up more and (2) My wrist speed needed to be lower to get it going. Both of us enjoy using the product and is definitely helpful for my elbow issues.

I am a mechanical geek. I love tech. However, I also love and have to know, "How does that thing work. As a young boy, I loved Gyroscopes. This Gyro Ball is a mechanically brilliant freaking device. especially if you like fidgets ( like me ). Once you learn the secret, that is really not a secret and you learn. How to get this thing going. (euphoria) You will have that instantaneous feeling of euphoria. WOW factor moment. It's a work out. As you move your wrist, you start to spin the inner gyroscope and as the spin increases with corresponding wrist movement. Led’s, inside the gyro start to lite up. A whirling sound starts to be heard, The colors (3) Start to change with the revolutions. They are representative of the force this gyroscope is producing in resistance. What a freaking workout, Your Grip will strengthen, your forearms as well.You walk away , with a feeling of immediate gratification. All this for only $15.00Semper FI.BartaBingBartaBoom

This product has been a game-changer for me. I keep it in my truck and use it almost every day on my way to work. When I first started, even 45 seconds felt challenging, and it was tough on my left hand to keep it going. But now, I can easily go for 5-10 minutes on both hands. Not only do my wrists feel healthier, but I also no longer worry about my hands or wrists when benching. I feel stronger and more stable overall. I wholeheartedly recommend this product to anyone looking to improve wrist strength and stability.

You folks that treat this like it’s a self propelled toy, need patience. It’s not a toy! It works but you need a little practice. You don't just get it spinning then stop and watch it. There is no time set! It will continue to spin as long as you provide minimal motion. Watch the video. Hint: use minimal clockwise tilt. Can’t emphasize enough. Use the lanyards If it gets going and you let go, it can hurt you or break something.Have fun! Your wrist will get stronger too!

Everything was perfect
