I love these tanks. I usually miss when they are in stock because they sell out so quickly. These are Boges attempt at making a DC Tank. Id say its a very big win. They are superior in quality to the Smoktech Tanks and they can use both Smoktech and Boge replacement cartomizers (XL with or without the flange).
For $6.99 your getting the Tank (5ml), Cartomizer and Drip Tip. Its also free shipping. If your a big carto tank user like me - I think its a win win!
