Next time I will order only the original flavor.  The other flavors did not suit me.  Too much of an aftertaste.

Ex Input:
I agree with the other review, these chips are not for a sore mouth or tender gums. The chips are very hard and the taste is delightful if you enjoy the salt/vinegar combo. Unfortunately, every bag I received in that case was over cooked! They were very dark and only a few golden brown chips in each bag. They definitely need to improve that!

Ex Input:
Coffee tasted bitter and burnt.  Didn't like the 1st cup; kept open mind; 2nd cup not any better. Wish I could return the remaining 48 cups.  One star for fast shipment.
