Kinetic Spinning Desk Toy Ball, 1.54'' Fidget Toys Ball for Adults Anxiety ADHD, Optical Illusion Toys for Christmas Birthday (39MM, Rainbow)

It's so fun to watch. It does make slight noise so be aware of that if you're sensitive to sound

Received this nice little decoration for my work desk. First day, I could give it a really good spin and it would keep going for a minute or longer. Now, on the second day, even the best spin stops in 10 seconds or less. Seems to have already had something wear down/loose inside the mechanism. Still looks good but the fact it has already dropped the "performance" to about 1/6 of original in 24 hours, I don't expect the spinning aspect to last even a month.

My son begged for this item, and I was hesitant because of the price. We kept watching videos, and we finally purchased the rainbow one because it was mesmerizing in the videos. When it arrived, the colors were very muted and virtually indistinguishable. My son tried it once and hated it. We are so disappointed in what was sold versus reality because of the appearance and that it doesn’t spin independently for more than a very short time. The videos paint a different picture, so be prepared for the dose of reality with your purchase.

I must confess I only had the pleasure of playing with this fidget for a few minutes before my Autistic 16 year-old stole it from me with a gleeful "Mine now". It lives on his desk and he spins and spins it while doing school work and playing games online. Every attempt I have made to snag it back has been blocked, so I can safely say it's a winner on the most desired fidget scale.

I bought this for a friend and ended up buying one for my daughter and one for me. By the way we are all adults😊. No assembly required. The material is pleasing to touch as well as pleasurable to watch it spin. Great quality!!!!
