After getting tired of the cheap set I got from AutoZone, I ordered a set of Ram factory versions from my dealer in a color to match my interior (Canyon Brown). My young son had just bought a set of Weather Techs for his 2017 and we compared them. The material seem to be the same and the molding lines have me convinced that Weather Teck probably made them for Ram.
Anyway, no gripes at all with the Ram set. They fit perfectly and clean up well. I've yet to find them slippery.
