This is my 2nd fidget and probably the best. It is for people that need something complicated to help them think. Especially if you smoke a pipe, cigar or like coffee. It's the spinner for you. Five star *****, but I do have complaints.CONS;It's tiny, that's good and bad. I expected it to be a bit larger.It's well machined, and the main frame peace that holds it together is very sharp, knife Sharp to be exact. Solution, it's worth it to take it apart and apply some sandpaper around the outer edge the elliptical oblong frame holding peace. Do not sand either of the Precision cut holes where the bearings go through.PROS;The chain has no sharp edges.It's ball bearing, plus brass bushing. Spins nicely.Comes fully assembled, but you do need to sand the sharp edge holding piece as described above. Careful attention should be given in exact component placement and facing as originally assembled. While you cannot tell any differences between some of the pieces, they don't always fit together the same way. And when tightening them down things that didn't bind before, may bind when reassembled. If you have retained the exact reassembly placement (I suggest to draw diagrams and separate parts if necessary) of the original components and facing and you see binding. I suggest, that you back off slightly all of the screws and wiggle everything while tightening gradually in small steps, so that everything seats properly.Everything should be quite loose when properly assembled. Do not force anything, and tighten to within reason. Note, allen wrenches provided are low quality and can damage screw heads. Special note, the washer above the holding plate should bind to the brass bushing and it's screw, but this binding washer should still turn but with resistance when holding the allen wrench. This is how to tell if you got it correctly assembled. The washers on the exposed sprocket side should be completely sloppily loose and wobble about. That's how you know if you got it put back together correctly.It is employing 2 bearings for maximum speed. The ball bearing, and the brass bushing. Both sprockets are honed internally to Glide and wobble on the brass bushing. This is done so that the teeth of the sprocket can stay aligned to a spinning chain. Incredible ingenuity yet simplistic. Again, *****. WORTH The Money $24.99, But buy only Stainless Steel as Colors or Gold rubs off and looks bad.

This is such a cool thing? toy? device? idk, but it's great for reigning in my attention from being scattered all over the place. Fun and expertly made.

Generally, I don't like spinner type fidget toys, but this isn't exactly just a spinner. I have larger hands, so I can one-hand "orbit" the sprockets in my palm, or holding it tucked in the web of my thumb and index finger. I can "tank" roll the toy by holding the large sprocket bushing and rolling the chain on my arm, leg, or a rough surface. I can work it between both of my hands, And of course I can spin it by either large or small sprocket bushings. Spinning generates a "whirring" sound from the chain working around the gears that just tickles that "gearhead" spot in my soul. I like mechanical fidgets, and this is one of the better ones I've come across so far. In fact, I've improved it some by taking it apart (with the supplied hex keys, thank you!) and filing the sharp edges along the back of the sprocket frame and reaming, polishing, and lubricating the bushing contact surfaces and lubricating the squeaky chain. The machine oil I used gives it a machine shop olfactory aesthetic, and it's all smooth as silk now. The best part of it is that I COULD improve it on my own with minimal finishing effort - and that to me is part of the experience and aesthetic of a quality fidget toy perfect for someone with ASD and a fascination with machine shop goodness. ;)

These look really neat, very industrial looking fidget toy. It seems to be of high quality and durability. It can be taken apart for those that enjoy the process of reassembly.But as a fidget toy, kinda meh. It spins if you're willing to make a jack-off motion. It rolls around in your hand, but it would be better if both gears were the same size. You can roll it around like it's a tank tread, but the chain has poor traction.Weirdly, it's a fidget toy that performs best when displayed on a shelf.

kind of small for the price, but is a great fidget toy for my desk while I'm working

Well made and a perfect size for the hand or to carry in the pocket. Colorful. It's a fun, unique, little fidget and reminds me of my son's joy of bikes.

Strong addition to my EDC fidget item rotation. Well made, chain is not greasy, moves smoothly, interesting feel in the hand, just heavy enough. I have the "gold" one, which is all stainless covered except the sprockets are slightly goldish. Not completely silent in use but fairly quiet.

It sounds like a dumb complaint, and I do have smaller hands. But I can’t comfortably fidget with this with one hand otherwise I would bring this thing everywhere. I love how it feels weight wise and it’s constructed well. I bought it to replace a flash drive that I would fiddle with in a similar motion. Such a shame. Was going to return it but my husband ended up playing with it for a little bit and losing it haha

Purchased this for my son months ago. He still plays with it when he’s fidgety. Works great!
