Example Input: Peice of crap dont work cant pick up nothing here so when I called company to send it back the company refused to reimburse me so thank God I had Amazon insurance
Example Output: negative

Example Input: This cookbook isn't simple, as claimed. I bought it for the photos and supposed ease of recipes, but the truth is most of the stuff in there is flavorless and more difficult than necessary. The most frustrating part, aside from it not being recipes most people really eat, is that the 'simple' recipes require having other recipes made before-hand, and then lists them as an ingredient. I sent it back.
Example Output: negative

Example Input: It was very well packaged, the matress was well wrapped and compressed into a small roll, after unpacking, just allow a few minutes for it to expand. I would recommend carry it to the room before unpacking because once it is fully expanded, it becomes much bigger and hard to carry. It is a great mattress, the firmness level is just right - firm but not too firm. Seems well made and no off-gassing. Overall I’m very pleased.
Example Output:
positive
