You couldn't pay me to buy a cart!I tried it a few times and within less than week I throw the thing in the trash with the battery. Something about it just doesn't "feel right" to me. Maybe e-cigs have the potential to save lives of tobacco smokers idk? but weed vapes and the sound of the oil burning and cheap battery pens etc. I'd just go edible route if I wasn't prone to combusting every once in a while or dry herb vaping.
