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.

Input: Consider Input: We have this model about a year now. It hasn't worked right from the beginning. We often had trouble closing the top. Sometimes it doesn't work at all. Other times it works like a charm. When it works like a charm, it's not uncommon to find coffee grounds in the cup. It's a mess. I bought the same model for the office. The experience was similar. Sometimes it makes a full cup of coffee other times it doesn't. Sometimes it won't even work at all. We have to turn it on and off and cross our fingers. A friend reports these problems as well. I agree with the reviewer who says, DO NOT BUY. A waste of money for the machine,for the K-cup that couldn't be used, and an exercise in frustration. We're in the market for a different brand. When Keurig first came out, they had the market. They have a lot of competition now . . . which hopefully will make it easier to find a machine that works well.

Output: Negative

Input: Consider Input: The initial taste does hint of something, but then the apple and grape juice filler comes to fore and dominates the after- taste. Comparing this to the Black Cherry drink, Kiwi Berry has a better taste and after taste. However, if you would have told me that this was the Black Cherry flavor, I would have thought that to be true. I could not note any significant difference between flavors. The carbonation offers no benefit in the taste or feel category. The price is high - about $1 per 8 oz can. If I want juice, I'll stick with real juice without the carbonation.

Output: Negative

Input: Consider Input: After being disgusted by the brown water created by the Cafe Escapes dark chocolate cocoa, we were THRILLED to find these dark chocolate cocoa k-cups. Delicious!
Output: Positive
