I haven't had any luck at all. I'm vaping kanthal claptons in my clone Haze dripper tank thingy. I cant take it anymore. I had a few good experinces with the DNA40 but most of the time it was "god damnit where is the kanthal". The only authentic stuff I use is the subtanks, I also have some stuff from fasttech. None of it works. Legit or not temp control is a finicky bitch. Last attempt was with sweet spot vapors Ti. It doesn't work. I loaded the csv and all that. Right at first it was great then I put my kid down for bed and came back to hot legs and burnt. Hot legs, Hot legs, Hot legs, Hot legs, Hot legs, Hot legs, Hot legs, Hot legs, Hot legs, Hot legs, Hot legs, Hot legs, Hot legs. I gave up.
