Input: Consider Input: I baught this kind of cereal from Wholefood. Since this was the first time I tried this brand, I picked 3 kinds: multi-grain, oatmeal and brown rice. Oatmeal was all right, but the other two smelled like they were already stale(the expiration day is May 2013), and they tasted bad too and sticked on my throat when I tried them. My baby cried and refused to eat them. The customer service of Wholefood was very nice and refunded me. I don't think I will buy this brand of cereal again.

Output: Negative


Input: Consider Input: I am very pleased with this selection.  I have not tried the other hot cocoa brands for Keurig but this one is awesome!  I bought the milk chocolate.

Output: Positive


Input: Consider Input: I finally gave in and bought these expensive chews because the others we have used only last a few minutes. The package claims to provide "hours of entertainment" for your pet. What a ripoff! They didn't mention you would have to buy a case of these things and feed your dog a big meal of bull hide for it to last hours. I have a seventy-pound mixed breed dog, Roscoe, who is four years old. He doesn't chew for entertainment like a puppy would, but when it comes to eating, he is a real chewer. The kibble he eats is the size of puppy kibble and he thoroughly chews every bite. Well, I just gave Roscoe a bully spring and it was thoroughly chewed and eaten in under ten minutes. My seven month old puppy isn't quite as fast as him, but she too can put one away in minutes. The pig skin rolls at the supermarket last longer, and they aren't advertised and priced in a way that victimizes customers.


Output: Negative
