Example Input: I ordered this DashMat for a specific vehicle, it was not the correct mat. I returned the original one and they sent me an exact duplicate of the wrong mat. I can't seem to get the correct one and therefore it sits in a box!!!!!!
Example Output: Negative

Example Input: The product seemed like a good idea but wish I had read all of the reviews before ordering. The product is not sturdy at all. It didn't come with the number of screws noted on the instructions so I had to go out and purchase more in order to finish putting it together. That was after I spent way to much time trying to decipher the instructions. Also, the clips that hold the bag to the frame are very tight and very difficult to put on and remove. I've torn every bag I've used. I hate wasting my money; but, I'll have to buy a better one.
Example Output: Negative

Example Input: On the surface, this book offers startlingly beautiful language and heart-stopping imagery. But its offerings merely begin there. Levine, a master of metaphor and tone, uses these 18 surreal parables to critique power dynamics and to expose the oppressive mechanisms of family, relationships, body and gender. Often simultaneously funny and disturbing, these stories will resonate years after a first reading. Her expert use of the surreal is often called Kafka-esque, an overused and misused literary cliche that, for once, fits the bill. Her keen grasp and expression of humanity's politics precisely suits the Kafka legacy. Her expert use of language and imagery remind us that writing really is an art.
