We have these suto delivered.  They are a great healthy sub for potato chips and the snack bags are a perfect size.  Great crunch and we enjoy all the flavors.

Ex Output:
Positive


Ex Input:
This oil is wonderful. I've had almond oil that was so strong it overwhelmed what I was using it for (salad, cooking).  I loved the flavor of this oil and will be buying more.

Ex Output:
Positive


Ex Input:
These chips (all flavors of the variety pack) are really terrible.  I have thrown away a lot of them and suffered through eating some of them.  They are over spiced and nasty.

Ex Output:

Negative
