When originally produced in England  these we're the best chips I had ever tasted but unfortunately since they were bought out by the US conglomerate they now taste plain nasty. Hard rather than crispy, are much thinner than they used  to be and lacking any  flavour , a real shame.
Negative

I consider my Sheltie to be an intelligent dog, but the noise of the toy makes him back away. And I can't tell you how many times I've "demonstrated" how to get the kibble out. He just waits until I do it. He could care less about the thing, and he's very food motivated.
Negative

These popchips are a great alternative when you need a munchie, crunchie snack. They are much lower in calories/fat than regular chips and are portioned controlled. I especially like the barbeque flavor or the salt and pepper flavored popchips.

Positive
