we still use the regular 510 atty's (from Totally Wicked), back then it was quite a learning curve, but now it goes kinda natural.
even with the VG liquids we use they don't clog up, only the taste deminish after 1 or 2 months of every day use. witch is solved with a boiling-in-water-session and they are good to go again. most of them seem to have a life-span for about 6 months, some even longer, then the draw deminish a bit, still working tho.
major point tho is that the batts needs to be propperly charged, if not the taste, warmth of the vapor and the vapor itself becomes a tat too weak, also the atty starts to clog up in the long run.
have to admit, reading reviews about other atty's it does sound tempting to try something else, coz some really sound that they can give me a better vape, but when i read how easy it is to kill them and how more important it is to propperly feed them, i think, why should i even try. it took me very long to get the hang of these, i quess i'm not ready to give that up yet.
