Precision matters
Measured with calipers, dimensions are spot on. Very quiet operation under load.

Good quality bearings
They work well for my 3D printer upgrade. One star off because packaging was a bit crushed, but bearings were fine.

Great for small motors
Used these for a custom drone build. They handle the RPMs well without overheating.

Perfect for my RC Car
Bought the 6mm bore set for my drift car. Smooth spinning and low friction. Highly recommend.

Mixed bag
Most were great, but one out of the pack of 10 had a slight grind noise. Replaced it easily though.
