Spinner Fidget Toy For Anxiety, Focusing, ADHD, Autism, Quitting Bad Habits I have to say that this Tri-Spinner spinner is fantastic! It is the third one I have purchased. The first one was from Etsy and the other one was 3D printed and I did not like it at all. This is the most expensive one at 24.99 but it is worth the price that you pay, and best performing spinner in my collection so far. It is not 3D printed. And I think that makes a difference. It has a solid weight and feels. It's pretty well balanced. I got a spin time last night of two minutes while holding it. It is well finished and seems that it is injection molded. This is the best, Fidget Spinner. Maxboost Tri-Spinner Fidget Spinner Focus Finger Toy Stress Reducer for Kid and Adult\u00a0 I mainly chose this option over the others because I have personal experience with Maxboost as a brand and trust them to make a quality product. Placing this on a flat surface, I was able to get this to spin for over 4 minutes when I first got it. As time's gone by, this had reduced, but that's to be expected considering I use it quite heavily (and therefore drop it a lot as well). I struggle with dissociation in response to anxiety, and this helps somewhat with grounding or just keeping the dissociation at bay in the first place. It's very discreet and doesn't make too much noise, so I haven't run into any problems using it under my desk at school or even at work (and I'm a cashier at a fast-food restaurant). Overall, I am really satisfied with this Tri-Spinner purchase, and it's definitely a quality product.
