I've been using my PT2 now for almost a week! Vaped lika biatch the first couple of days and then it started to make less and less vapor and started getting dry vapes with a full tank, changed the coil today and back the vapor was again for about a hour and then I started getting dry burnt tastes running at 3.8V, so I have to vape at like 3.3V - 3.6V, made a duel series coil yesterday coming in at 1.8Ohms and got dry vapes, took some wick out and got gurgles. took it out, stripped it bare and put the old coil back in, the coils that came with it is suppose to be 2.2Ohms
