Example Input: We generally like Aden and Anais products, but this fitted sheet doesn't seem so fitted. I'm actually concerned it's so loose that's its unsafe. Defective or are they all like this?

Example Input: I purchased this item to use for my sons prom send off, the only balloons that were able to be used were the latex ones, no foil balloons could be used, also the discription shows a 2018, I was sent a 2019, which means the day of prom last minute I had to go and purchase the correct numbers which cost me an extra 40 dollars... I'm so disappointed..
Example Output: negative

Example Input: This camera has a high pixel count and is lightweight enough to carry around. Recently my friend always invited me to take a photo with my camera. Boston is in the fall, the maple leaves are very beautiful. It's really time to buy this camera.

positive
