I doubt very much that they're used relays. The Smart Relays don't have a core charge, where would a business get a supply of used, working relays to modify? My reading of their website was that these are new Porsche relays that are opened up and modified. If there was an oily fingerprint it was just a matter of dirty hands and lax quality control.

Amazing to me that no one has opened one up and reverse engineered it. At least no one has posted about it.
