This is a great product. I was a chip-a-holic and knew I needed to cut back on them. Then I was introduced to pop-chips.I have found my alternative. These chips are great! Low in fats but high in flavor. I purchsed a mixed case with multiple flavors and was not disappointed with any of them. Consider this product for your alternative to the high fat chips available everywhere. I am sure these will catch on and become a big hit.
