I think you might have gotten the AAP Driveworks confused with the Microguard from Oreilly's. The Microguard is WIX made and identical to a Napa Silver.
As mentioned the DW is Chinese made. The construction looks to be comparable to WIX, but IIRC, the efficiency is nothing to write home about. I want to say they don't even have much info out on them..
