I think I said I would report back on Umbavape WTA (unflavored). Whelp, I was still having major cigarette cravings from my mom's visit, so I loaded up a tank of it pretty heavily, and either it works, or I'm just feeling better. I don't understand how they make it clear and tasteless (pretty much) but they do, and the quality is VASTLY better than Mother's Milk WTA, for less $$ so you really can't beat it. It was comparative to Aroma in potency as best I remember, although it's been a while. I will probably order more as at that price, it really cannot be beaten. I was pleased.
It doesn't taste good OR bad, so if you are going to do like I did (50/50, but I have REALLY WANTED a cigarette) I'd use a flavorful juice, although I must say, I probably did not need such a high percentage, but it CERTAINLY did the job.
