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 Input:
Thought I was getting a really good buy on these until I read the label. The dosage amount of Glucosamine/Chondroitin is vague. It appears I need to give my dog an entire bag to get him 500 mg of glucosamine. Too expensive for me. The dogs love them, so if you want to give them an expensive treat they'll love, go for it. If you are trying to get a preventative dose of glucosamine in a treat look elsewhere.

Ex Output:
Negative

Ex Input:
Sorry to all you champurrado fans, this is not the real deal, but an artificial version, and WAY too sweet. Please compare to others 'hecho en Mexico', and get yourself a 'molinillo' while you're at it! ps: I use almond milk to make mine!

Ex Output:
Negative

Ex Input:
Love them. Hardly notice any aftertaste from sweetener. I don't agree with some of the others that didn't like it...Will buy again...

Ex Output:
Positive
