I didn't know that ashtray was a flavor that people actually used. That's an interesting piece of information; I figured it was a joke to antagonize smokers with who were reluctant to switch.
It's just another supplier trying to give a close analog flavor. It's not harsh or nasty like an actual ashtray. Nothing like that at all. Just a catchy name?
I wound up buying a bigger bottle of it & use it quite often. It's about as close to the real thing I believe your gonna get. I enjoy tobaccos & the Wyatt Earp & Dark Vapure are also very good if you want a basic tobacco flavor. I'm not sure which is my favorite, they're all a little different. I mix them with each other as well as some different flavors. They are good all alone & makes for a great go to base.
That's what's nice about their samplers. I picked mine mostly based on reviews but had to wing it on some. The tobacco flavors I picked are a mix of analogs but some are semi-sweet with a little cigar in there too. I have to admit I was after that analog flavor. Parkes Vaping has more tobacco flavors than anyone I've seen.
They are as close as they come IMHO, & plan on ordering more. They also seem to have a sale quite often & will let you know via email.
Hope that helps.
