I ordered 3 of the flavor packs; the cinnamon roll, salted caramel, and chocolate.
Taste wise, the chocolate has been the best so far, the salted caramel is pretty good, but can have an odd aftertaste, and the cinnamon roll is very bleh (I think in trying to replicate the yeasty flavor of a roll it ended up tasting kind of off).
The flavors themselves are on the weaker side. I typically have to use 2-4 times the serving size to actually get a good taste of the flavor. And it's a shame there isn't a way to sample the different flavors before commiting to a whole 100 grams, cause if you aren't a fan of one you ordered your kind of just stuck with it.
