MetMo Brass Gear Train

Very well engineered. Great tactile feel with a satisfying sound that’s not intrusive. Nice and easy to move, doesn’t put strain on thumbs and well designed pocket size. Would recommend for ASD relaxation and restful mindset.

Absolutely brilliant fidget, extremely well made and very satisfying and tactile to rotate. There's very subtle clicks as each tooth engages but quiet enough to use in an open office space. I would love to see a planetary gear version of this!

The product and pictures of the product are different from the one shown in advertisement videos. In the promotional videos you can see both stacks have the same number of gears, 7 each for a total of 14 which would only give you a ratio of 1:8192 and my guess is that they noticed that which led to them adding another gear for 15 total to get to the advertised 1:16384, which is great, however, they could only easily fix this, by adding a gear to the stack that doesn't have the locking pin cause otherwise the locking pin wouldn't fit because it would be to short. Because the locking pin stack is now 1 gear shorter than the other means that the last gear of that stack has only a 1:8192 ratio, meaning you'd only need 8192 rotations of the top gear to fit the locking pin back. So for the full gear train experience you'd have to make the bottom gear of the locking stack rotate twice to get the intended 16384 rotations. Normally I would let this slide due to being a technicality however since MetMo prides itself on accuracy and precision I just can't in this case which is why I'm giving it a 4/5 stars. It's still a fun and fantastic product working (mostly) as advertised. This is not a too serious review just something that's bugs me, loving precision and accuracy myself.
