great bearings, cool packaging and customization

Extremely quiet and smooth.

(Disclaimer, was sent these by the brand, but was not paid or even told to leave a review, I just figured I would given my experience.)

This is a well done product. Beyond just the smooth bearing experience, the unboxing also has some fun surprises like a randomly selected bearing cover alternative (the default ones say “HYENA”, but my alternatives say “BOSS” and I know there are other options, so it’s somewhat of a blind box in that sense).

The tool to switch covers works great, no complaints at all. I actually first tested the bearings in a 3D printed fidget spinner and was very satisfied with the results.

Each box comes with 8 bearings, a large number of covers (maybe so you can trade with friends who have different ones?), and some spacers. These seem well made and are easy to install.
