My dog loves it, he is a bit of a crisp connoisseur but these toys are his favorite alternative, and I can make his snacks healthier.
The packet crinkles like a crisp packet as do the little toys inside. If I have any criticism it would be al of the balls should be treat holders and maybe add a squeaky, he does love a squeaky almost as much as a crisp :)
Overall, a great toy that'll see plenty of use.
