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.

Very disappointed
I was really excited to receive these snack packs as someone who recently is doing keto. I was very disappointed that they have no flavor, not lightly salted or anything and were almost stale/soggy. Keto stuff is expensive and I’ve found some good nut mixes before, these just are not it and maybe sat too long?

"OK" taste
I was excited to try these but was disappointed when I did. They are "OK" taste wise..no bold flavors that is for sure. They will be nice on-the-go to throw in my purse but I wouldn't buy them again - not only because they taste rather bla but also because they were a but expensive.
