Good quality

One size was tight initially but loosened up after use. Great speed improvement.

Smooth operation

Replaced steel bearings in my fishing reel. Much smoother cast and retrieval.

Perfect for my drone

Spins incredibly fast and reduced motor heat significantly. The MR105 fit was exact.

Fragile handling

Dropped one during installation and it cracked. Ceramic is brittle so be careful.
