    I bought this after seeing a recommendation in a fidget facebook group. My preferred bearings are those that are not too loose, have some whirring noise and tactile feedback, and are easy to spin (not heavy or draggy). This pretty much checks every box. It resembles a goldilocks bearing. It should not be too loud, too quiet, or too loose. Although it is not my favorite bearing in my collection, it is an excellent replacement for bearings that are too boring or too slow. It appeals to me.
