Note - there is a white wick in the atomizer bridge that is needed to wick
juice from from carts. SOme people mistake that cart cart stuffing stuck to the atty and pull it off. If you pull off that wick then that atty will no longer wick well from carts.
Re carts in general - after not many reuses, the stuffing starts to behave badly. I recommend blue foam stuffing instead. Strictlyejuice sells precut blue foam for standard 510 carts. STuffing for smaller carts can be cut from those. Or the bulk material for 10x the cost is Marineland Rite-Size U Bonded Foam Sleeve from Petsmart aquarium dept.
And I agree with the 2 above - if there are cartomizers available for your ecig then try some.
