Good Value
First time buying a damaged box item, this exceeded my expectations. Great value.

Pretty good, but not to OEM standards
These rotors are okay, but the inner diameter of the rotor where the parking brake engages is larger than the OEM rotors. It's not off by a lot, but still requires adjustment of the parking brake to account for the size difference.
