PROBLEM: For those who love salt and vinegar potato chips, this is the one to choose. The flavor is zippy and tart, with no unpleasant chemical aftertaste like the less "natural" versions of this snack. The 2-ounce bags are just right to share at lunch. The chips are a little greasy, and that's why I've given them 4 stars instead of 5.

SOLUTION: 4

PROBLEM: My 8 yo is a Kettle chip addict so I was so happy to find snack size bags for his lunch!!! Great quality and much cheaper than in the stores!!! Will definitely be buying more!

SOLUTION: 5

PROBLEM: But the taste got sickening quite fast. It also makes a really weird stench/smell when you are microwaving it. Sometimes it would hurt my tongue when I am eating it. All in all, I threw the rest of them away after my 3rd bag. It might just be me but I can't say I would let the guests of my home try these so I can't recommend them here to anyone.
