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: We bought this to limp us through not having a stove for a while. It works great! We use it to saute veggies, boil water, scramble eggs.... anything a small bottom pan can do! Heats up super quick and very easy to clean. Even once our stove is repaired, it will be in regular use in our home.
Example Output: positive

Example Input: I have read all reviews before I bought this, luckily, I received an item with any issue. The stun gun can make loud noisy like other buyers said, the flashlight is not bright enough, but It can blind the attacker. I have try the stun function and my friend said it make a huge painful sense.
Example Output: positive

Example Input: WHen I first received this product, I was very disappointed. It simply would not open for any of my cats. We even had them chipped for the express purpose of using this feeder! After a week, we finally brought the cat back in to check the location of their chips, and lo and behold, the cat who needed to use the feeder was missing its chip entirely!! I did not know they could fall out, but apparently ours did and that's why the feeder wasn't working. The vet replaced the chip for free and now the feeder works perfectly. It took about a week to train the cat to use it, but she has no issues with it and the other cat is constantly disappointed that the lid is closed. One note, though. It says that you can program how long the lid stays open after the cat leaves. In fact, there is just a 3 position switch. This is good enough for us, but it doesn't work the way I thought it would after reading the literature.
Example Output:
positive
