So I bought buttercream mint as one of my first flavors. Did not like it. Really bland and flavorless, no mint flavor, just a slight sweetness to it. So I put it away for awhile, shook it everyday for two weeks, lots of time uncapped. But I figured it was a lost cause. If I didn't remotely like it out of the box, I didn't think it would really change after steeping. Picked it up today thinking "eh, why not" filled my tank a little, gave it a go. WOW! Nothing like it was out of the box! I taste the butter, the cream, the mint, taste just like the candies!!!! After a few puffs I filled up my tank all the way, this one is a winner! Lesson learned, steep, steep, STEEP!! Any other flavors that require lots of steeping?
