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 these on August 22nd and installed them right away. It’s been a little over a month and around 5,000 miles and they are completely warped. Very disappointed with the overall quality of this product.
Example Output: negative

Example Input: Looks nice out of the box. Charges quick and touch screen is very responsive. That is the end of what's good. App that the included paperwork directed me to install is from a 3rd party site. Once downloaded, my antivirus warned me that it was an adware program. I installed it anyways. I then tried to pair the watch with my Samsung Note 8 and it would not connect. Tried other apps and it still would not pair. Not a very smart smart watch. Will be returning.
Example Output: negative

Example Input: I had high hopes for this from the reviews. It is sitting about 16 inches from a window and I allowed the 14+ days for it to acclimate. We had a series of snow storms, a blizzard, freezing rain and varying daily temperatures shortly after receiving this. It has NEVER changed for any of the weather. Once in-awhile I will pick it up and shake it like a snow globe just so it will look pretty for a couple of hours, but other than that it's a waste of money. Disappointed!
Example Output:
negative
