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++++

Output: 5


Input: Consider Input: I bought 21 0z freeze dried liver. Half the container was filled with powder instead of pieces/chunks. I feel I was betrayed by the company. Hence I did not get what I paid for

Input: Consider Input: If you are a farmer with lots of farm cats, this is the perfect food - and because it is primarily sold at most farm and fleet stores I think that it is meant for farm cats. The ingredient list is marginal quality though, which can be expected. Most of it is corn and grain products, with a few meat by-products here and there. Better than Iams but not by much.  I've been feeding my cat on Diamond Maintenance for 2 years without a problem but I will be switching to something with more substance soon. If you're looking for a cheap option for lots of cats, this is a good product to buy in bulk; but if you have a domestic cat you wish to keep around for awhile, I'd suggest something else.  And hey, if you're looking for a good alternative, get Chicken Soup For The Adult Cat formula. Great stuff, doesn't cost a lot, and is much better than the regular Diamond food.
