I'll go ahead and review the 3 I've tried so far.
I will start by saying, this is the first time I've bought from an online site and liked all the flavors I bought. 3/3 flavors taste exactly as described, I applaud them for that. Many other sites I always get at least one or 2 flavors I dislike or don't taste as described. They are now sold at my local B&M so I buy them at the local shop now.
Butter Cream Mint: Not good fresh out of the mail. Even after I let it air out overnight, still not good. Thought it was done for, let it steep for 2 weeks. Randomly picked it up one day and BAM! Flavor! It is sweet with a slight butter taste. The mint is there, it isn't a blow your hair back menthol, but it is smooth and light mint. Tastes like the candies, but steeping was 100% necessary. =)
In Vino Veritas: I've been really tempted to try this one for awhile. I love wine and champagne, but I hardly ever drink, so this seemed like a good way to enjoy a flavor I love. Went to the B&M for this one, they let me smell it in the store. WOAAAAAH! This stuff smells STRONG! Smells just like white wine, it's just overwhelming. I was afraid it would taste as strong as it smells. Read some reviews, turns out this one doesn't have alcohol in it no matter which line you buy it from. It also doesn't need to steep. I filled up a tank and gave it a go. To my surprise, it tastes like wine! It literally has that tart wine taste, I don't know how they did it. Sweet when you crank up the volts, bitter on lower volts. The flavor is as strong as other VV flavors, it isn't overpowering like I thought it would be. I must say bravo, never had an alcohol beverage flavor that actually tasted like that real thing! Would make a great fruit flavor mixer too.
Vanilla Blackberry Swirl: This is my favorite so far. It is sweet like cream but tastes like blackberries as well. Actual blackberries, not the fake cough syrup flavor. Needs to steep to get the full flavor, but not bad fresh either.
