Authentic or Clone? Yet another industry embroiled in the debate of manufacturing quality, Short and to the point. I'm a retired Aerospace Design Engineer. Many times we had to re-manufacture OEM parts from a PMA Cert Machine Shop to get parts quick and installed in an aircraft. I know when I have a piece of junk in my hands. I have 2 Stingray X, Genesis, M-16 clones. with 2 RDA and 2 RTA ( Turbine and Kraken). I have no complaints at all about the switch functions or any other build feature. Use a light lube on threads and button shaft when you re-assemble your mods and you will have no problems. I also have a
smok Fury-S and K100 (My Vapor Store). Great function and bargains.
