In this task, 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.

Example Input: I bought this for my daughter and we were so excited about it. It worked for maybe 20 minutes tops... I thought that maybe my batteries were bad.. nope. We tried several different batteries and it still doesn’t work. It’s a cute puzzle, I just wish it still sang the song!
Example Output: negative

Example Input: The slots are a bit small for my liking but this case is amazing and my 3 and 7 year old fight over who gets to use it. Guess I’ll have to get another one.
Example Output: positive

Example Input: Purchased these because they were on the Top quality end. Not cheap in product!! They are really nice, great weight, sharp, rounded ends, and a case to keep everything together. As a beginner I wanted something that would help me out and not hurt my dogs and these are really good at an affordable price.I found these grooming items to be of high quality and make grooming my Mini Schnauzers quite easy. The scissors are sharp, and the comb really does its job. Would buy these again!
Example Output:
positive
