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: This rack arrived so twisted/bent that it can not be assembled. I wanted it for an upcoming trip but I will not have enough time to return it, wait for the new one to arrive before my trip. Absolutely useless junk with no QC. I will just return this item and go to a local business to get one. Thanks for wasting my time.
Example Output: negative

Example Input: This band is pretty awesome! I wasn't sure about the adjustable part of it but it made my gym bag lighter, now I don't have to carry 3 bands. Adjusting is kinda hard but that's a good thing because it will avoid it from loosening up while you work out. The rubber ending with logo also prevents it from sliding all the way out. I'm not sure if it was made that way on purpose but it's a good feature. All in all, I am very happy with it. I used it on Smith machine while doing leg presses laying down and during squatting. It doesn't seem that way but it adds that extra burn you want when you get used to your workouts after a while especially on inner thighs which is a difficult area for all women.
Example Output: positive

Example Input: This product sucks! Not only the package arrived damaged and all the bolts/nuts were all over the place, the instructions are very bad. It took me over 4 hours to put it together.
Example Output:
negative
