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 got two bottles for my newborn with no issue. On the third bottle, discovered a dropper that wasn’t built into the cap. Not sure if it’s a defective batch or what. (Which means you’d have to wash the dropper every time... not ideal at all.) I submitted for a return/replacement and the fourth bottle I got had the same issue. If this is just a new design, I’ll definitely have to just switch brands. :(
Example Output: negative

Example Input: All lights had been intentionally sabotaged. Packaging was intact from Amazon but when I opened shipping box the individual light boxes had been opened and the pull chain switch had been yanked out.
Example Output:
negative
