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.

Pinching the center of one of the gears and whirling it around is fine, but what I do 99% of the time is just kind of knead it in my hand. The only sound is each chain link gently tapping the gear (if you hear squeaking, oil the chain links just a tiny bit). I have a bunch of fidget spinners that don't hold my attention for more than a few minutes at a stretch, because, as it turns out, measuring spin time just isn't that interesting. This, though - this is a good one. It looks neat to boot.

I thought it would come with Allen wrenches,but did not. I also got a silver one, pretty sure I ordered a gunmetal.

I bought this for my early onset Alzheimers husband. It's a cool fidget toy that is reminiscent of a till he might have used. Here carries it everywhere.

break it in a little bit and it is a joy to fiddle around with. well worth the money and solid construction

From the first day I felt that I became addicted to this nice piece of art.Very cool and well made.

The more you use this the better it gets with some play it's broken in a bit and play's smooth has not fallen apart yet so far pretty fun have used for a few week's now.hope this helps

Really cool to play with

Best fidget spinner I have ever buy. Very costly, it takes about over Rs 5000 in India. But built quality is good stainless steel fabulous build quality. Good spinning and the sound it makes while spinning is like a real gear spinner.
