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: Works great! I have two other similar products and this is by far the most powerful. Especially for the price! Shipping was quick and easy without issue.
Example Output: positive

Example Input: After two months of use, I have to say this is the earphone I want. No distorted wire, great audio performance, decent battery life. Way better than Airpods except for portability.
Example Output: positive

Example Input: This pole saw is extremely unbalanced. It is very difficult to use when attached to the pole. The saw does cut well for an electric chainsaw. My biggest complaint is this thing is a nasty mess. It constantly leaks a pool of oil all over anything around. I have oil stains on my workbench in the back of my truck in my driveway due to the leaky nasty mess this thing creates. If this thing was not such a pain to repackage I would be sending it back. I am very displeased with this purchase. The third time I used this the chain broke and flailed around. I was cutting a 1” branch when this happened. Yes, it did cut my hand. This product has no business being sold.
Example Output:
negative
