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 ordered a size down since I like the bands to feel snug and secure, but it was wayyyy too big. I cant even wear them because they slide down or roll up. Its unfortunate because I was so excited to order them! The material on the band also is not sticky enough to adhere to the pants. Wish I would've returned when I had the chance.
Example Output: negative

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: Great knife for the price. Perfect EDC fixed blade. Knife guys know 2 is 1, and 1 is none. So in addition to my utilitarian folder, this is it's fixed blade partner. It holds a nice edge, sheath could be better, but it works fine. I horizontal cross draw carry, and it fits right on my belt perfectly. I din't want a large fixed blade, as it becomes cumbersome and weighty. I try out different blades all the time, and so far this is the knife I keep coming back to. I modded the scales a little for a better grip, but I would definitely recommend this knife.
Example Output:
positive
