I chose to go with clones for my Mechs and RDAs.
My first Mech and RDA was a tobeco crown RDA, and an Ehpro Maraxus, the crown was and still is great, the maraxus however had some issues, it only took a few dollars to get it hitting hard, it needed a magnet upgrade in the switch, solved all the problems with massive voltage drop and hot button.
I do have a smoktech Magneto, which is as authentic as I will ever get, because it is still cheap, but it also hits pretty well, magnetic switch, telescopic.
I have a Helios on the magneto, and it is a great clone RDA, again no problems with it at all.
My 2 newest purchases were.
Copper penny mod clone, not sure who makes it, but it is absolutely great, contacts are silver plated copper, has a magnetic switch, it hits like a train, it does get tarnished very fast being copper, so weekly I take it apart and clean it up.
A tobeco copper tobh RDA for the penny, another great clone RDA.
But probably my favorite clone mod I have is, my Morpheus, came with copper contacts, upgraded magnets for the switch, as well as the spring, and 3 tubes for 18350,18500 and 18650.
The RDA I have on the Morpheus is the
smok caterpillar, it matches it like a charm, I did have to bore out the airflow holes on the caterpillar to vape anything lower than 1 ohm though, but thats easy enough I just used a pointed file in my drill to bore them out just a hair.
If I only bought authentic that collection would be a stupid amount of money and my wife would have shot me in my sleep for sure.
Actually that collection of clones cost me less than 1 Authentic setup.
Maybe one day I will get an authentic, but it is rare that I have that much play money and nothing else to spend it on.
