At one point,i thought maybe it was my wicking causing mine,but i can't see how since i only get the leaking after vaping it down to a 1/2 tank,i can never figure out exactly where it's coming from though.I will definitely agree though,by far the best i've used,which is why i keep dealing with it.I took the condensation plug that comes with it,and opened up the air slot today,so i installed it,hopefully when it leaks it will route it out the air holes instead of all over the mod.Even with the issues i've had,i'm still on the lookout for a 2nd one though.I have Boxxers with both the original glass and the Odis unbreakables and find neither leaks. I have tried all the rba/bridges and for me the Boxxer and the EUC 0.5Ω ceramics are the best
