Here's a quote from the boge vs smoktech theread I was telling you about, I thought you might be interested in reading this one:
im really liking the 1.5ohm dual coil XL smoktek carts. although my first 5 pack had 3 that werent working properly. i tried some of the smoktek 1.25ohm, they work nicely but they gum up quicker and the juice has a very slight burnt taste. 1.5 works best for me on my SLB kGo.
