Perfect for my drone project
These micro bearings fit perfectly into my custom drone frame. Smooth rotation and no play.

One defective unit in the batch
Mostly good, but one SUS628 bearing was noisy out of the box. Support replaced it quickly.

Good quality but packaging could be better
The bearings themselves are excellent quality stainless steel. However, some arrived slightly greasy due to packaging.

Excellent rust resistance
I use these in a humid environment and haven't seen any corrosion after three months of use.
