Example Input: My girlfriend love this as a gift & she hasn't complain yet, so I assume it's worth buying in my opinion! :) it also good for when u have more time to sit on the floor and play ps3 games!!! It is not cheap but quality does come cheap. If you want really comfy, get some pillow or something, otherwise It's okay.
Example Output: Good Review

Example Input: The book was easy to read, and filled with valuable information that is worth the time spent reading it. I bought it in conjunction with a project, and, as part of it, read this very good guide on how exactly they did things down there at Area 52. Not only does he get his information, but writes it in such an entertaining way, even for non-scientists.

Good Review
