So I've had my Ego-T for about a month and it's great! I like the throat hit, battery life and basically everything about the unit. Very well engineered IMHO. The ONE drawback I found was the limited 1ml tank cartridges. I just upgraded to a new tank system and it is FANTASTIC! If you find yourself with the same dilemma I HIGHLY recommend this tank. It was about $22 from vaporescence in Dallas (those guys are great) and definitely worth every penny.
