So...What are the verified differences between the authentic and the clone?
I don't think anyone is able to answer this until we find someone who actually has acquired both.
The design is the same, the difference might be manufacturing tolerances, but I don't have an authentic so I don't know how much better the tolerances are an the authentic (if they are better at all). I did mention already that the tolerances on my clone are perfect. But that may not be the case for all of the clones. It is a metal mech mod with a few delrin insulators. There aren't many parts to it.
I did decide to replace the screws on the top cap of mine after taking it apart multiple times, due to the small screw heads stripping a little. This was not a big deal for me, since I have so much gear and keep the spare parts for all of my devices, so I just found four screws that fit. It might require a trip to the hardware store for someone without a lot of extra parts already, though. The authentic could be the same way, however, that I do not know.
The biggest difference is probably going to be where the devices are manufactured and the price. Sometimes, it is nice just to have an authentic
device because it is endorsed by the authentic community and the machining was paid for by the original designers. And sometimes $350 is too much for a copper box that is bought with the main purpose of being used regularly.
I am still using my copper Raptor clone daily. It is a very frequently used mech, and I have quite a few similar mech mods.
