yes and yes
MUCH better battery life.....but the other part of the equation that most overlook....with a standard 510 battery, the first 4-5 drags are wonderful, beyond that, the power begins to fade almost immediately. With a Tornado/eGo setup, you get that "fresh off the charger" power for hours and hours....in fact, no noticeable difference until the last couple of drags. You will produce consistent and
voluminous vape with an eGo/Tornado
+1 my vote for the eGo/Tornado
