This tank has been hit or miss for me. I am running it on my MVP 2.0...My thicker juices with custard flavoring and heavy flavors come through really nicely, juices with higher PG seem to just completely leak and gurgle after a few puffs. I literally just filled to just under 2ML with blueberry (with a higher pg, I think 70/30), and couldn't really get the voltage and flavor right, and once I was getting close, I checked the fill lines and it had dropped to 1ML - floaded and all over my battery. When it does work I do get some nice flavor...Puffing on my Opus this morning was completely satisfying. The only downfall is that the draw seems to be way too airy...I actually have to inhale 3-ish times on the same "puff" to get good vapor production. Anybody else had problems like this? Is there a fix for the airy draw? If I am just running a crap tank, what would any of you recommend as a replacement? Don't want to spend an arm and a leg, but a local shop has an Aero on sale. Any help is greatly appreciated!
