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 am so disappointed with this product I was very pleased with my previous vivoactive I just wanted a different style of watch to look more feminine while still having a Garmin. And that is about the only good thing about this particular watch it's battery life is horrible any little bump will have the thing flying to a whole different screen I would never buy this product again
Example Output: negative

Example Input: I never wanted to be a dog parent that needed one of these, but here I am. I have a year old puppy that will not listen when it comes to eating things he's not supposed to outside. It's super easy to use and I love that there are different settings. I mostly use the vibrate but when I do need to use shock I have to use at least 80 for my dog to even notice it. My use of the collar is to have my dog drop whatever is in his mouth from a distance so a lower setting might work for your dog. There's a charge port to put the collar and remote on which is awesome. The collar is also super long but you can trim it to fit.
Example Output: positive

Example Input: Piece of junk. Super cheap. Worked only for about a week and then wouldn’t even stay lit for 10 hours to act as a night light for my kids. Constantly had to be plugged into the wall and didn’t come with an adapter.
Example Output:
negative
