MIni Aerotank here too. Like it a lot. Vapemail today should be bringing me the somewhat larger Aerotank V2. The Mini would actually hold more or less enough (I keep three of them going with different flavors), but I find when the liquid level gets down to where there's still as much as 13 or 14 mm showing in the tank, the vape changes and gets noticeably lighter. I'm hoping the V2 either maintains the vape quality tilll the liquid level is actually reasonably low in the tank, or at least the increased capacity of the V2 over the Mini will all be vapeable before the vape lightens.
Anyone else noticing this behavior? Using 100% VG probably isn't helping, but all the juices are thinned with about 3 to 5% water. (Hmmm... they all were. I'll have to check my notes, I was experimenting and I think some of the more recent ones might be blended with a little less water than that.)
