I'm sick and tired of coils dying in less than a day and having to throw out bottles of (relatively expensive) e-liquid because of what I think of as a compatibility issue.
I do understand your frustration... but I'm not convinced it's a liquid issue, but rather a coil issue.
I can vape any 50/50 or 60/40 liquid in my RTA's for a couple of weeks, even when they are pretty disgusting they still taste ok and never taste burnt.
Those old nature vape coils we put in those old style tanks were better than most of the stock coils around today.
