Smooth rotation
Very low friction. I use them in 3D printer idlers and the print quality improved due to consistent filament feed.

Perfect for drone motors
These bearings are incredibly smooth. I used the S684 size for my racing drone and the performance improvement was noticeable immediately.

Good but pricey
Quality is undeniable, but they are more expensive than standard chrome steel bearings. Worth it for specific applications though.
