Example Input: I thought these would be the perfect answer. Sadly, I guess the pressure with which my Keurig machine shoots the water through the k-cup is too much for the disposa cup, because every single time I tried it, coffee grounds were spewed up through the tiny hole in the lid of the disposa cup all over the inside of where the k-cup sits in my keurig. And yes, I used them properly.  So the issue, at least in my Keurig machine, seems to be with the lids. Some have suggested its a design flaw with the Keurig machine. In either case, these disposa cups were NOT the answer for me.  Biggest waste of money ever. I cannot recommend.
Example Output: 1

Example Input: Great price for an excellent chip. At about 80 cents for a 2 ounce bag these are a bargain as well as a very tasty chip. Everyone I've let try these has been impressed and commented on how good they taste. I've yet to find a Kettle chip that disappointed!
Example Output: 5

Example Input: I was a little skeptical when ordering this product. With everything it had going for it I figured there had to be a catch. Wheat-Free, Gluten-free, Non-Dairy - I wasn't expecting much in the way of flavor. I was pleasantly surprised that, while it seems subdued, there is flavor and it's alright. I can taste the chocolate & the coconut predominately. As it states on the box, they are "moist & chewy". I wasn't a fan of the texture at first but by the time I got to the 3rd bar it was fine.  What I didn't like is that one bar has 180 calories (80 of which come from fat). So much for a healthy "whenever" bar.  15mg of Cholesterol, 130mg of sodium (yikes), 23g Total Carbohydrates, 2g of dietary fiber, 8g of sugar, 2g of protein.  It also states that there are 180mg Omega 3 fatty acids, 9 grams of whole grains, & 0 grams trans fats.  The numbers above are for 1 bar which = 1 serving.  This product contains coconut, eggs, soy, and almonds. It is processed on equipment that also makes products containing peanuts, other tree nuts, soy, and milk.  So this isn't something I would personally chose to get again. They're alright in terms of flavor but they just seem to have too much of a downside when inspecting the label.
