Bought juice and coils here and both lasted me 4 days before coils where burnt and juice turned brown

X4's last me 2 weeks and their house juices don't have too much sweetener to ruin the coils as quickly.

Yea for whatever reason i dont get much use out of my tfv8 coils from there. But the ones i buy at good nature last me weeks for the same coils. Only conclusion i can draw is that a to z buys knockoff coils, whether they are doing so knowingly is another thing. Btw good natures coils are cheaper also.
