ok so i just got some stanless steel dual coils and a i think aluminum drip tip and to be honest...im not liking either the drip tip or the carto. no matter what i vape i get a metal taste with my draw and it makes me feel uneasy and nauseated also the carts get very hot im using one on my ego T pass through while on my lap top i set it down on my chest and about burned myself lol im going to try my rubber tip and see if theres a difference and will update tomorrow but as of now im not a fan..love madvapes 100% but not really feeling these cartos at the moment. oh and root beer is amazing lol..
