You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.

[EX Q]: Complete, protein-based nutrition.  My dogs love this...although I'm not sure the pibble actually tastes it, she inhales it so fast.  ;)  Regarding the other users who have had diarrhea issues:  My gastro-picky GSD (is that a word? I think other GSD owners will understand!) has had this as well.  Initially, I overfed this food, thinking that he needed to be eating the same amount as he had been eating the other stuff. You feed MUCH less of this product.  It is nutrient-dense, and not all filler like other foods.  If you over-feed, you increase the risk of unpleasant side effects.  It's a bit pricey, and I haven't broken down the cost per day, but since you feed less it might be competitive with other brands if someone was inclined to "run the numbers".
[EX A]: Positive

[EX Q]: I ordered this product because of a good price deal.  Amazon shipped accordingly, absolutely no problems there.  However, the taste of this product was horrendous.  It tasted as if someone through chemicals in a cup and told me to brew it.  I personally will go back to buying Swiss Miss in a can and just using the Keurig to give me Hot Water, cheaper and much better tasting.
[EX A]: Negative

[EX Q]: I've been feeling extremely tired around the late afternoon. As a software engineer, this is entirely unacceptable! So, I asked the nice lady at the counter of my local Whole Foods Market, for something that will give me that extra energy I need to get through the day.  She excitedly returned with a suspicious little green bottle. Over three hours after drinking whatever that was, my brain is still working at unnatural speeds. To summarize my experiences: I believe this works.  She did explain that I needed to drink plenty of water with it, which I personally feel helped the energy level. So if you're feeling tired during the day and hate coffee, give this a shot - preferably before you eat anything.  Woot!
[EX A]:
Positive
