Snack pack
It’s okay for a quick little snack. The package was fresh. Texture was crunchy. You may enjoy it, but you would have to try it on your own. I felt like I was missing something or wanting more.

Alternative Snack Option
Nice alternative to the stuff available at the local corner store. Will not win any taste awards. Portion size is excellent. Satiates the snack cravings. Odd after taste from one of the mix items. Confused by taste, is it old or odd!?

A nice snack
These are just salty enough, easy to pack, have a good taste and satisfy my need to crunch. They have a decent flavor too. I like them.
