Must be it. I called mine the LeakTank Pro. It leaked better than it vaped. Did nothing but gurgle. Vapor was meh. Flavor was the worst out of anything I've ever tried. I went strictly cartotank after that & stayed that way until I got my KFL. Now I've got 2 KFL's & 5 IBT's.
*L* I moved away from cartos TO the PT2. Got tired of the awesome taste of polyfill and changing roasted coils every 4 days.
All my PT2s have performed solidly. Flavor is average. They really need to change the wicking system and/or material to upgrade the flavor..
