I have been wrestling with my target stuff. I got my first tank used and it was leaking really really bad..but i chalked that up to coil. So i bought two more cause the taste is just that good..i got one tank and then also the full set in another color. My new tank is leaking as well but not from the af like the used one. Its leaking under the tank. When i take it off my mod there is a puddle of ejuice. I wipe it away and watch and it beads in all these little places. I then have the whole screen glitch over heating thing going on in my other color. Im waiting to hear back from the seller on a replacement but are there any fixes for any of these things? ive been checking o rings and even replaced one, ive been making sure to not over tighten the coils. I actually left the white tank that leaks off the mod last night and on a paper towl but standing up and this morning it was nice and wet with ejuice. Its a slow leak maybe 1/4th of a tsp but thats alot if its on your mod. I just cant seem to win with these.
