Ask questions, post your favorite brands and strains, share your least favorites, battery preferences, etc. Discuss and enjoy! This is not a forum to discuss why traditional atomizers are better, all these devices have their purpose and it is impossible to beat the discretion and convenience that a cart offers when travelling or in public places. So what batteries do you all prefer for carts? I had been using a dr dabber battery before upping to a variable voltage, but now i find i like buttonless batteries the most for carts- like from the blu ecigs. The worst cart I've ever used and tasted was a Spliffin.
