Ya, my madvapes cartos seem to stay wet regardless of how full the tank is. I can only come to the conclusion that some carts are just better than others. I have tried more carto's then I can count and settled on the madvapes 2.0 ohm carto's and tanks. I have yet to have a madvapes cart or tank fail on me. I don't do any ohm checks, don't own a volt meter, just found what works for me. I also make sure I use 30% VG/70% PG juice. This seems to be the best combo for me. Since I decided this was the route I was heading, I have not had one problem.
