...I'd return them for a refund. Brake rotors matter too much to take risks.

To me this is one more reason to stay away from eBay brake rotors. The previous owner of one of my (now former) cars had put eBay slotted/drilled rotors on the car. The material itself was garbage. I never saw anything rust so fast in my life.
Edge damage is far less problematical than interior damage in rotating machinery. I've had disks far more severely damaged than that finish 35 lap sprint races at the old Riverside Raceway.

I do agree that these Chinese made disks are of lower material quality, but the fact that they rust is not a good indicator of this.
