I don't know what my nasty taste came from(used atomizer,fresh cart,recharged batt) but whatever it was it was unsmokable..I'd compare it to the taste of the smell of a sharpie marker,very chemicalish and just awful.

I tried a hot water vinegar bath for the atomizer,if anything it made it worse.Then I shot some steam with a teapot thru it and that seemed to do the trick(although I can taste the nasty every now and then as an undertone) Perhaps another steam is needed.

I think no matter what system,or from where..ecigs are tricky and need patience and tinkering.While I miss analogs simple light n go..ecigs are still worth the hassle imo.
