Example 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.

Example Input: This is a great product. We tried it at the beach the first time and loved it. The cashew crunch was not as good. We bought a case of the almond this week. Just great!

Example Input: I used to buy these as healthy snacks at my office cafeteria and consider it better than a bag of potato chips. These taste very crunchy and tasty. Given the kind of unethical food stories we read about China - we need to see some kind of assurance and facts on the processes that the manufacturer is following to make these. You just cannot import food stuff and sell in the US as gourmet snack food - there needs to be data backing this. Few example of Chinese food (yuk ...): (1) Melamine(kind of platic) in baby food and milk (so wide spread that 80% of milk in China contained this plastic in 2008) (2) Honey contaminated with ciprofloxacin (antibiotic) - because of which it was banned in the US (3) Soy Sauce made from Human hair (not joking google it if you want) (4) Spurious drugs exported to African countries. Need some good facts and quality controls from the Manufacturers that the chinese producers are complying with some good quality controls.
