+Really really tasty +Much healthier than almost every other potato chip +A variety of flavors, consider this a huge sampler -Sea Salt & Vinegar is crazy sour. Personally, I think they overdid it on the vinegar. -It's hard to stop at one serving, but I take this as a sign of a good snack :P

Positive
