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: I used it for a week and half and it seem to work as described. I don't know how well its going to work for over a long period of time, but it is cheap so it probably wouldn't last that long. No leakage of air or anything yet. It was the right size for me and I am 5'2, it might be small if your over 6' I'd imagine. Anyways, I recommend it to people who are looking for a temporary place to sleep.
Solution: Positive
