These are great because they're only 100 calories per pack and are just as good, if not better, than other chips out there. The "Original" style taste exactly like Munchos, but don't come with the high calorie count. The other flavors (Sour Cream & Onion, Salt & Vinegar, Salt & Pepper, Cheddar, and BBQ) are all delicious, as well.

Ex Output:

I have a 15-lb. schnauzer-mix puppy. She's easily bored, extremely destructive & likes puzzles. This looked perfect. It takes a bit of work to get food out so I knew this would occupy her for a while. The screw-on lid at the bottom of the jug was virtually seamless and very tight. When I ran my fingers over the seam before giving it to her I could barely feel it. I gave it to her at 8am before I went to work. I came home for lunch at 11:30 and she had COMPLETELY destroyed it! She located the seam and, somehow, wedged her teeth into it, worked her way around the circumference and pried the lid loose. She then chewed the lip off of the jug all the way around so the lid cannot be put back on it. She was lying there calmly and the food was all gone, so she had clearly long since finished all this in the 3.5 hours since I had given it to her.

Ex Output:

I bought this for my husband who has been drinking espresso all his life. On a recent trip to Italy we bought the lavazza rosa espresso and I was able to find it and order it on amazon. I bought the gevalia just to try something new and based on the reviews I thought it might be a good idea. My husband loves it and actually prefers it to the Lavazza. I just bought another 3 pack. we use a stove top Bialetti and this is fine for that type of maker. Highly recommend!!!
