I personally bought a few of those, and they are just gorgeous.
The brass/copper body has a good heft, and the bearing is small - type 688 ZZ, I believe.
Among the ones I got, the spin time varies anywhere between 3m:20s to 5m:48s.
I know it's a replica of the original CKF Pepyakka v2.0 spinner, but it's quite good.

The original 27mm button caps are made from thin Aluminum, which is fine, but I decided to machine a better cap. Here's the result...took me quite a while to make it:
The "Sphinx UFO" Spinner with my custom Stainless Steel 30mm button cap
Then I thought "Wouldn't it be nice if there were gem stones in those UFO window holes"...
