I have been vaping for 3 months now and was about ready to give up when i bought some 510 cartamizer omg they are the best investment i have made since i have been vaping I get tons of vaper and they last all day no more dripping or messing with cart mod they are great they are disposble so they dont last forever but you get 5 cartmizer for 10 dollors not bad and you can refill them.
