I had a minor leak when I filled it way up to the top. I like to push a new
tank to see how much it can tolerate. Now I fill it mostly to the top and there hasn't been any issue.
My build is 26g kanthal, 3mm ID, 0.72 Ohms, 28W. My tails are real short...you can just barely see them sticking out under the chamber cover. Vapes like a dream, and every hit feels saturated. I even vaped it until the
tank seemed bone dry by simply tilting the liquid onto the tails. I implore every one to try the short tails at least once. You'll free up space for
juice and avoid any excessive cottony taste...not to mention, it's probably better for over-all wicking to have shorter tails.
Edit: forgot to say that I'm about to buy another.
