Firstly, Good Mornin MVPeeps. Now dat the formalities is outa da way ...
Kinda depends on ifn you like da crunchy type or da creamy ... I'm thinkin creamy cuz crunchy would be kinda hard to vape so in dat case, yeah, it tastes like PB ... only it doesn't stick to the roof of your mouth. There been some here that even throw in a bit of Grape but I call that just plain sillyness ... lessen you like PBJ's, then maybe so.
KimberUltra2 ... short answer ... yes.
Longer answer ... multiple is kinda a relevent term, I spose ... could mean a couple but that's usually 2 or even a few which is usually at least 3 or it could be several 5-7 or a bunch which will take you to between 6 and 10 or more. Personally, I've got a gaggle which means what the heck am I doing with all of these? I've built my collection from 6 EVODs to also include 2 iClear 30's, 3 ProTank 2's, 11 ProTank 2 minis, 6 Mini Davides, a couple ARO poly's and a couple ARO pyrex. All my pyrex have some kind of juice in them. I now have the luxury of using the EVODS to sample juice (cept known tank crackers), rinse them out (sometimes even with vodka), let them dry (sometimes) and try another juice but then if you don't rinse the tank out and add another flavor, you run the risk of stumbling on a combination you don't want to put down.
Having multiple tanks, what ever that amount is, is also more convenient ... just grab a tank and go. Now, if you hang around this site for very long, you're going to hear how good this juice or how good that juice is and unless you can excercise a lot of constraint, you're liable to end up with ... lemme see ... 73 bottles of juice.
Granted, there are a few several that are duplicates 'cuz I don't want to run out and a few that I'll save for when I can't taste anything and a couple of "what was I thinking"
?
Of course having more batteries or mods adds to the convenience. See where this is going?

And you thought you were going to save money by quitting smoking, right?

Welcome to your new habit.
