I am so frustrated I could scream. I am posting in the newbie forum however I have been vaping for a year and bought countless $ of equipment, built my own coils, tried all kinds of heads. I had settled on a Vaporesso ceramic ccel head for my Pico Mega/Melo 3 and been using that awhile with decent results but suddenly getting dry hits and dull flavor. Every head I have tried it seems one works, then the next one doesn't. Sometimes I get 120ml through them no problem, sometimes I can't get a day. I have cleaned my equipment, changed batteries, checked o-rings and everything I can think of. I am vaping at 30w with .5ohm usually. Building my own coils was a pain in the a** and I could never get the same results twice. Can someone please tell me a foolproof inexpensive replacement head for my Melo 3? I also like my Cleito but can never get heads that work in that either.
