Review on 🛹 Afrowlle ABEC9 ABEC11 Skateboard Bearings: Ultimate Performance for Roller, Skateboard, Longboard, Motors, 3D Printer, Fidget Spinners by Cashout Harden

The 608z bearing in the middle, next to the tube marked 10pcs, has dents like someone tried to install or remove it with a hammer drill. I may have received a customer return. In any case, it was enough for me to replace the defective bearings in two window air conditioners. I think the ABEC9 claim is just hype because the bearing is the same as any other bearing I've looked at, nothing special and when it spins it slows down like a normal bearing.
