It's an ok fidget gyro and it kinda cool and different. It pretty well built and I don't think it would be easily broken. It fun to fidget with and helps slow down my mind from racing thoughts. So it's good for distraction and concentration at the same time. Good for ADHD PTSD AUTISM or just goofing around with. I'm not overly fond of the half sphere on one side. I think it should be open on both sides for a better experience. But it's ok because it's different than others and different is good for me. I think I'll get another one and cut the other side off for fun and see if I can do a good job at it and enjoy a different experience. But I'd say most kids and some adults would enjoy have one to fidget with and pass time worrying about nothing while playing with it as I do. I only gave it a 4**** star rating because I don't think it's the best value but not too bad of a deal. I guess, that is an opinion of the fidigeter and the buyer. And if it keeps someone occupied and out of mischief then it's an awesome value. I'm still happy I have it and if you know someone who enjoys fidgeting with something different than this is for them or even for yourself. It's worth trying one in my opinion. And it would make a great stocking stuffer.
