I picked up a SmokTech Zmax to try something different. I have been vaping for 4 years and have been using a Provari for a while. I don't know if it's the variable watts but I am getting a much better hit off my Kanger Protank II. Not bad for a $59 clone. I had some regret after seeing the Lava Tube v2.5. I guess I will get one of those pretty mods soon. The menu of the Zmax is kind of confusing and the 510 threads get crossed easily but I like the vape.
