I have a Kanger Evod Mega that someone from work gave me. She had lost the charger, so I went and bought one to try it as an ecig. I've yet to find a pen device that I really liked, and this one was no exception. The tank and draw just suck in my opinion. So, I picked up a new box mod for my vaping needs. Can anyone recommend a concentrate tank / atomizer that they have used personally? I primarily want to use it for budder and possibly some bubble hash in the future. Im not big on concentrates and dont really have any interest in wax, shatter, or oil. Is it worth it to try this with a 1900mah vv battery, or am I better off tossing it and buying a vape that is made for herb/wax like an atmos?
