Good quality, tight fit
Quality seems high. They were a bit tight in the housing initially but loosened up after use.

One was noisy
Most were fine, but one bearing had a slight grind noise. Good for the price though.

Perfect fit for my buggy
These bearings swapped directly into my 1/10 scale chassis. Smooth spin right out of the box.
