I couldn't make them work for me.

I got coffee, waffle, and choc fudge bavarian cream, and they all smelled exactly the same to my unrefined nose. I probably would have enjoyed them anyways, but the first few drops made me cough too much (can't stand any PG at all). I really wanted to love them but alas. However, you might really like them, especially if you do better with a pg/vg mix than pure vg!
