Yeah, so far so good, but I'll dry burn after every fill just because you can with the e2's without shortening the lifespan of the coil or burning the wick. Just means no top-offs, but when you've got 4ml who needs a friggin topoff? Great stuff Stormy. I'll need at least 2 more at some point, one for minty and one for fruity/candy. I'll hit you up when my wallet's a little less hungry for sure. Can't wait.
