I know what you mean. I haven't used my rdna 40 in several days. The feeling of a box just doesn't feel right in my hands anymore. The fire button doesn't feel as smooth. Outside of the vape quality, this mod is enjoyable all around. I did order a zna clone to put a dna 40 chip inside so that i can use that for my temp control wants. In also going to try and modify it to fit an 18650 with the shorter tube. Then I'm going to use an inductive coil from an old toothbrush to fit in a dremeled bottom cap. Then I'll use a conductive ring with a tiny spring terminal to feed the charge through a flat wire to the chip.
