How do you figure that? To most, 1:1 means an exact copy. Not exact copy except substituting *whatever*.
Yeah, 1:1 does not mean "exact" copy, it means the dimensions and function is 1:1. Materials used can differ a lot, especially when it comes to wiring workmanship, chips used, steel grade etc etc... I don't need to go on, these things are made on the cheap to look exact, why do you think they can knock them out so cheaply?
