High quality steel
Very durable bearings. I've been running them at high speeds in a mini turbine project and they hold up well without overheating.

Great variety pack
Having access to all sizes from 1mm to 9mm in one store is convenient. All dimensions were accurate when measured with calipers.

Good value overall
Quality is good for the price. One of the 2mm bearings felt slightly tighter than the others, but the rest were perfect.

Fast delivery
Arrived sooner than expected. Packaging was secure and each size was labeled clearly. Will buy again for my RC cars.

Perfect for my drone build
These bearings are incredibly smooth. I used the 3mm and 5mm sizes for my motor mounts and there is zero friction. Highly recommend for hobbyists.
