I'm not only not the president of Vaporesso, I'm also not a member. The search is over!! After going through god knows how many vape devices, I've found the PERFECT mod. The Vaporesso gen air 40. Zero leaking, awesome hits, great flavor, fits perfectly in the hand, holds a lot of juice, has adjustable air flow and has a battery that will at least last a day with heavy vaping. I decided to try it after seeing good reviews for it on Vaporfi. It's only about $27. If you are up in the air about which device to get, get this one!
