I would love to get a mechanical mod and other goodies! I am an Electronic Engineer and have only used regulated or hybrid to this point due to perfecting my coil building and getting an atty ohm meter (much easier to usee than a regular digital volt/ohm meter). I started vaping this past Black Friday and have been building my own coils for RDAs/RTAs (FT Mutation X V4, UD IGO-W4, EHPro Kayfun Lite Plus, & FT Silverplay; the Fogger V6 in the pic negative posts broke so it's sitting for potential spare parts) since January/February. I've built coils all the way down to 0.2 ohms with a variety of wires. Like i said, being an EE I'm very conservative with battery safety regardless of having protection (you never know when it may not work and it's not worth pushing the limits)! Personally I am fond of twisted coils. Any way, it would be greatly appreciated since I don't have a big collection... yet! I plan on doing a PIF in the future, but as for now I'm just starting out.Thank you for your generosity!!!
