I bought these chips looking at its sale rank as one of the most sold chips on amazon.com. Unfortunately, I was highly disappointed. Way too much vinegar and they aren't like regular potato chips, some weird "pops".

Ex Output:
Negative


Ex Input:
These were NOT good.  They were hard and chewy and my kids wouldn't eat them.  That says a lot b/c my kids will normally eat anything!

Ex Output:
Negative


Ex Input:
4.5. Just water and large pieces of sardines. Open for all types of combinations of which I find the old whole grain crackers, quality cheese, a particle of mayo and mustard and a hot cup of tea, the most appealing. They do lunch in a hurry and snack times as well. Solid product. Even drank the water in which they are laid to rest and not too shabby. Sardines are good for a person, everyone agrees on that. Even a Sardine sandwich sounds about right in the next few minutes (the better the bread the better the sandwich...) so yes, 4 Solid Stars and I am hungry for the product right now, come to think of it!

Ex Output:

Positive
