Love that mod, but had enough of the ramp up heating so fast. I've dealt with it since I got it (about five months) and pretty much just got past the first pull full of heat and be fine until it sat for a while. It wasn't so bad on stock coils, and sometimes would not heat so fast at all but since I'm making my own coils now for my Toptank it seems to be a bit unforgiving on my coil so had to put in storage and take out my MVP 3.0 in it's place. I'm sad because the battery was awesome on that thing. I think I read somewhere that it was a common issue with that mod. Anywho, it's on vacation for awhile.
