Ex Input:
The candy arrived with some white waxy stuff on it; almost as if it had partially melted at one point. Tasted chalky. Not interested in a partial refund. Next time find a way to make sure candy is not stale.

This is easily the best potato chip that I have ever had. Look at the ingredients: Ginger and 3 types of hot pepper. How can you go wrong? Obviously, not for you if you don't like spicy food. But, if you DO like spicy food, you'll probably love these. They have that hot-with-a-hint-of-sweetness flavor combo that is prevalent in a lot of Thai food.

Raving reviews made me buy this for dogs. I have a lab mix a beagle and 2 Shepards that I got from impoundment and they're not spoiled. One chewed it to crumbles but left it on the ground and my Shepards have been burying them in the backyard. I wasted my money on this one.
