High precision confirmed
Used a micrometer to check tolerances. They are within spec for ABEC-5 standards.

One defective unit
Ordered a bulk pack. One bearing was noisy out of the box. Support replaced it quickly.

Good value kit
Most were great quality. One felt slightly rough but still usable for low speed applications.
