Input: Consider Input: I purchased this item as an alternative to traditional K-cups in an attempt to save money; however, this product did not work well in my machine. I followed the directions and read reviews to see what works best, but was not able to use the K-cups effectively. The cup itself is too weak and warps in my machine. I compared the shape before and after and there is a big difference; this K-cup seems to expand horizontally and vertically because the plastic is not strong enough. Also, the K-cup is shaped differently from the traditional K-cup. This is neccessary because it does not use foil as a topper, but does not seem to work. In the end, I had to clean up several coffee explosions in my kitchen to figure out how it works, but still could not use it effectively. Maybe I am not doing something correctly, but I'm sure there is also an issue with the product itself. While I do like the idea, I would not suggest purchasing this product until the bugs are worked out.

Input: Consider Input: These potato chips are DELICIOUS!  I have not had potato chips in approximately two years as it has been difficult to find organic chips.  Amazon lowered the price on these, and I finally had a chance to order them.  I most definitely will be ordering them again!  My family and I love them.  They are pure and void of all artificial flavorings.  The true flavor is present, and it satisifies the need for something salty, sweet, spicy, and crunchy.  A++++

Input: Consider 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.
