Mine came from Vapor4Life. Bad batch maybe?
I got my 555 from Rocky Mountain Vapor, and it tasted like saltwater taffy without the taffy (that is to say, all I could taste in it was salt with a very subtle nutty taste behind it). I can't stand it. Mine did not taste at all like peanut butter...
And it's strange. The RY4 and Caramel I got from them in the same order are fabulous (though the Caramel is better mixed with other flavors, like Bavarian Creme).
RY4 is the only "tobacco" flavor I've tried that I like, though it tastes nothing like tobacco to me...more like a Charleston Chew candy. The Dunhill isn't bad, but is still a bit salty. The Original Smoke Juice I got from Johnson Creek tasted like rotten walnuts, and the tobacco flavors that come in the "complimentary" carts that shipped with my 510 orders all tasted both sour and salty to me.
I still want to try the "Kent" flavor that everyone seems to rave about, but it's also out of stock just about everywhere I've looked. (Plus it will be nostolgic for me; Kent was my very first ever cigarette, back in 1986; though it's probably not best to celebrate that.)
I keep trying to find a true tobacco that I like, but they all seem too sour or salty for my liking. I think maybe because I got spoiled smoking Marlboro Blend No. 27 for the past several years, and it had a very distinct and original taste (kind of caramel-like).
