Today, I did the 1st cleaning on a T3, took almost 45 seconds, refilled and assembled, and we're off to the races. Ever since I started flipping the wick cap, I've had zero dry hits, and on the tank today before I did the cleaning, I vaped that sucker DRY. As in, last hit was last drop of juice. I've had close to 100ml thru this thing and it works better now than it did when it was new. Trying to figure out why I ordered so many damn replacement heads, at this rate, I'll never use them all up.
