hey everyone...just got an ego and some coca cola juice. im using the prefilleds that came with it and am having a problem with getting much vape from either batt or atty. do they just need broke in or are the carts that bad? they crackle and pop alot too. on the other hand my mistic is rocking hard with the stock cartos topped with the cocacola juice. smooth, tons of vape, and tasting great. im sure this ego will go well, but its getting kicked by my pilot cheapo
