These are so fun. Great fidget

The materials made of the design seem strong and long lasting. I really liked the fact it came with a couple different cases for transporting. It spins freely, but because of the awkward shape, it spins very well considering.**Update**After applying thread glue on the tiny screws, now it is sturdy! When spinning it before, I once unscrewed part of it while spinning. Now it even feels balanced

It’s a cool looking fidget toy and it gives you a tool to take it apart if you desire. It’s a little awkward to use with one hand to manipulate the chain around each of the sprockets. It’s well-made. It’s got good weight to it and it’s cool to look at. It’s limited in what it does so maybe I had it slightly higher expectations for it. As a collectible though it’s probably a much better collectible than it is a fidget toy.

Shipped quickly, and arrived in great shape. Love the product. A happy customer!

This is an interesting fidget toy. Great idea, but needs some improvement. Although I enjoyed the weight of the toy, the chain does not rotate smoothly around the exterior. The screws on both of the sprockets seem loose, and since this was manufactured so that both sides are not the same it feels uneven to hold and use. It does include a small screwdriver, so it is fun to disassemble and reassemble. When it was not frustrating, it was interesting to rotate the chain around the toy.

Fun to play with.

Cool to look at, not worth the $. The chain isn't tight enough around the gears.

This fidget spinner has been very helpful during testing for my grandson. He can slow down his need to rush to finish his test and concentrate on answering questions correctly.
