Yeah I scraped those foil seals off a week or so ago,cleaned and refilled the carts with some new 24 mg liquid, but I couldn't get rid of the stank funk taste, tried some dry burns on the atty then eventually started dripping directly on the atty and that has been all I've been doing for awhile now, just dripping ,and I am pretty satisfied with it even if these rigs aren't the best. I am thinking about eventually going to something w/ better battery life and a sturdier build.
Their juice is funky. Pull the fiber out and wash it under warm water. pat dry with a paper towel, and refill with your juice. That should keep ya going until you make a decision on another brand.
