Example Input: I have been looking for alternatives to made-in-China jerky. Because of - I presume - the amount of meat required to make real jerky, this has been a difficult endeavor. Even product lines like Milo's Kitchen source jerky from China while making the rest of their products - the ones they can process with fillers - in the US. True Chews markets US-made jerky treats but the meat is processed with other ingredients into a jerky-shaped chew that doesn't much resemble actual jerky.  Likewise, when I received these treats they were not what I expected. "Jerky," to my mind, means plain, dried meat. I thought the other mentioned ingredients would be added as a coating for flavor, but I expected a largely unprocessed product. In fact it is a cubed, compressed product containing significant amounts of grains and other ingredients as filler. My dog liked them but for the price there are other treats he likes better.  Maybe my expectations of a treat labeled "jerky" are out of line, but I know a lot of people besides me are looking for a US-made jerky treat, and in my opinion this isn't it. On to Blue Buffalo Wilderness jerky. It is several times more expensive but so far the only "real" US-made jerky I have found.

Example Input: Do not buy this product.  You will not be doing your infant any favors.  If at all possible, you should be breastfeeding.  (I know it's not always easy or convenient.)  If you can't then in my opinion the best formula is Earth's Best and even that is disappointing.  Basically, they dry cow's milk and remove all the natural nutrients then "fortify" with synthetic vitamins/minerals.  Pathetic.  Just buy whole organic milk, raw if possible.  There are recipes online to make it closer to human breast milk.  Sorry to be so matter of fact.  I'm losing patience for all these evil corporations capitalizing on the "green" movement.  OH and by the way the second ingredient in this garbage is sugar!!! Good way to start the diabetes/obesity while they're young!

Example Input: After my husband's enthusiastic reaction to the glutin-free Bisquick biscuits,I rediscovered an old Bisquick recipe booklet and used its recipe to make an "impossible" cherry pie. He loved it! Next I'll try the Impossible Pecan Pie. This is the first gluten-free product that my husband really likes.  I will buy again although I'd like to find it packaged/sold less expensively than on Amazon.
