Example Output: negative

Example Input: First of all, they took a long time to get to me. They come with no instructions. No way of knowing when they are fully charged. Charge doesn't last long, at all. And they scratch very easily. Very disappointed with this product unfortunately.
Example Output: negative

Example Input: I am so disappointed. This shirt is supposed to be neon pink and it doesn’t even come close. It is really ugly. It doesn’t look like the picture at all. I need it for school on Friday, so I don’t have enough time to order anything else.
Example Output:
negative
