Great for RC Cars
Used the 688ZZ bearings for my drone motors. They spin very smoothly and handle high RPMs without heating up.

High Quality
You can tell these are genuine German imports. The build quality is superior to generic brands I have used before.

Perfect Fit
Used the 684 deep groove bearings for my 3D printer upgrade. Exact dimensions and very quiet operation.

Good Assortment
The kit has a good variety of sizes. I wish there were a few more 685 sizes included, but overall satisfied.
