Ex Input:
The flavor of Big Train Hazelnut is not significant. One has to add a lot to have a flavor impact. Of the three Big Train flavors I purchased (including Vanilla and Irish Creme), Hazelnut is the least satisfactory. (Vanilla's a little better; Irish Creme is best--I gave that one 4 stars).

Ex Output:
Negative

Received product timely. Upon opening product found weevil infestation. Put product in freezer to kill weevils. Returning product would have been a nuisance.

Ex Input:
The chips were delicious. I didn't care much for the vinegar flavored chip but the other flavors were great. Didn't have any guilt eating this healthier snack.

Positive
