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: Plugged this into my Gear 360 camera, which handles 128 sandisk with no issues, this one shuts off after one minute, says the card is full and is buggy as hell- I would not order anything from this company, this is obviously a generic card with less than 2 megs of real space. I trusted their feedback ratings but got screwed. For 3.00 more I could have bought a sandisk and not had any issues, really upset.
Example Output: negative

Example Input: My cats are indoor, but I keep the windows and doors open, so fleas do have the ability to get in the house. One of my cats was starting to show symptoms of having fleas, and I opted to try this vs a visit to the vet to tell me he has fleas. Did some research, and gave this a try. I'm still on the first application, but flea issue has subsided. Also, not as smelly or greasy as other flea medicines.
Example Output: positive

Example Input: Buyer Beware!!! Although the OLD formula item is pictured, the NEW formula item is what was sent to me! I want the OLD formula because the NEW formula does a terrible job of covering gray. I have previously ordered several times from this seller, and each time, I received the OLD formula, which is exactly what I wanted. Yay! But THIS time, they sent me the NEW formula. And--get this!--it is not returnable! So now I'm stuck with SIX kits of the NEW formula, which SUCKS! I'm beyond annoyed! The picture on the description is of the OLD formula--so how is it fair that they sent me the NEW formula and I can't return it???!!! Ugh!!!
Example Output:
negative
