Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Example: I've read this book with much expectation, it was very boring all through out the book
Example solution: Negative
Example explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Problem: Recieved this item and it was broken. Tried to contact the seller but could not. As per amazon's return policy this is a non-returnable item. Which makes sense. Unless it is sold in a non-working condition. Was very displeased I could not speak directly with the seller and that amazon was of no help. Had to go through the manufacture to have the product replaced which is still a work in progress. Will not buy non-returnable items from this site again. Leaves too much room to get a defective product like I did and be stuck with it.
Solution: Negative
