Update: I've started pushing this tank to the limits. Only problem is I haven't found any. I'm now vaping on it from 8-15 watts and getting amazing results. No burnt taste and huge clouds. When I have the air limiter wide open, BIG PUFFY CLOUDS, as I close off the air I start getting throat hit and with it fully closed I feel the hit in my lungs.... WOW! I really love this tank.
