this makes so much sense since the major problem with the poly fill in the carts is that the atomizer only wicks half of the juice thats in the poly fill why not just cut off that half so the atomizer wicks all the juice? so i did as you said but only cut 1/4 inch of the poly fill off and have been vaping straight 50 mouth inhales with no topping off. still going... i bet ill hit 100 mouth inhales before the poly fill is bone dry. maybe even 200 inhales like some of those companies promise which is complete BS with the original poly fill design. but this design WORKS and i bet ill get a full pack of cigarettes worth out of one cart full. maybe... maybe... ill post again and let you know in a minute i gotta keep smoking this thing till its dry.
