Recieved my 2 G-50 clearo/tanks from The Vapor Girl Home Page: Where you can find the most beautiful items in the world! They are 5ml tanks similar in style and look to the Smok Pyrex Vivi Nova's except they are bottom coil. I have been on a quest for the largest capacity clearo style tank I could find, and I now have found it. Good flavor and vapor. The included drip tip will not win any design awards (it is just a straight tube without contours) but works well. Have replaced it with my own. Works on all my mods, no leaking so far, large viewing windows. Box includes one additional head. Paid about $14.00 each. Accepts ProTank heads. Overall: Love it.
