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: Bought this for a 2017 Ford F-350. Terrible product. Followed instructions exactly. Vent shades do not sit correctly so that when you put your window up it keeps going back down. Returned them and the company Auto Truck Toys only refunded 50% for a restocking fee. Product doesnt work but you have to pay for the terrible design. DO NOT BUY THIS PRODUCT OR FROM THIS COMPANY. You would be just giving away your money. I give this product and company NO STARS. I had give it a star otherwise it wouldn't allow me to submit
Example Output: negative

Example Input: Even though it isn't big, it is So Easy to Operate. Having Herniated Discs in my Neck & Bulging Discs in my Lower Back, I can operate this Machine without putting to much pressure on my Back.
Example Output: positive

Example Input: I purchased this one after I found out the 2 others I purchased from an on-line pet store were going to take 3-4 weeks to get to me. With a new puppy I needed one asap. So I purchased this one. What a disappointment! The "mesh" net was thin and easily ripped by puppy claws. There were NO directions with how to place it. The wall mounts were weak and fell off after one day. I was so upset thinking that the other 2 were going to be the same way and couldn't imagine why this net was highly rated. WELL when the other 2 came they were of much better quality. The mesh net was strong and solid, the wall attachments were big and once I stuck them on the wall there was no getting them off! There was a nice 1 page explanation of how to place the wall attachments to assure the gate worked best. WHAT a difference! The puppy has pawed at it several times and has not ripped it nor has the pressure he placed on the mesh torn the wall attachments off the wall - BOTH of which happened with this cheap version. Buyer BEWARE!
Example Output:
negative
