first of all thanks to everyone for telling me about the joye ego. purchased my ego from liberty flights and those guy have taken care of me. i have been vaping now for a month and love it! couple questions for yall, anyone have any side-effects for quitting smoking and switching to vaping? reason why i ask is because this cold weather mixed with vapor is destroying my nose, any ever experience this? also i purchase some cartomizers, stupid question but how do you use them? you drip into them? seem to screw right in, this correct? so far converted two others over to vapor from smoking cigs!
