I bought some 5ml samples a couple weeks ago and I had none that were perfumey/chemically. I also left them sit with the lid off for 24 hrs, then let them steep for 5 days. All of them were 80pg/20vg, normal flavor, @ 12mg.
My review of the flavors I got:
Wintermint - I love this one, great flavor very similar to Orbit wintermint gum - a new favorite
Keoke Coffee - I love this one too, strong coffee flavor with just a hint of cocoa and not sweet - another new favorite
Mt Dew - Ok, citrus taste but it's not Mt Dew.
Tiramisu - Ok, good coffee taste with something else going on.
Cinnamon Mocha Coffee - Ok, another decent coffee taste with other stuff happening.
Cinnamon Clove Dream - Blech (the clove gives it a burning tumbleweed taste)
I ordered more of the first 2 and a few other flavors during the weekend sale...looking forward to my 2 new favorites and trying some other new ones.
