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 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: i wear medium so i order medium but wayyyyy to big so i just decided to give it away n order small size instead but unfortunately it looks like an extra large just waaaayyy too big
Example Output: negative

Example Input: It worked well for me removing water from horse troughs. In a few minutes ( approximately 8-10 ) the troughs was empty ready to be cleaned and fresh water put back in. Saved a lot of labor. DON'T use a high pressure water source it will spilt the plastic and create a leak. Normal water hose pressure does the trick, live and learn I guess. Used glue and fixed the first one and reordered another one. If it came in metal, that would be great, but didn't see one. Enjoy, bottom line, It worked for me.
Example Output:
positive
