Example Input: I purchased this to replace a different pair of earplugs, but they did not fit any better. So far only one side works. They have good sound if you need the volume up high, there is no reduction to outside noise. Maybe someone will invent better, lighter ones soon. Don't bother with these, they're terrible. Sorry!
Example Output: Bad review

Example Input: This is a book which reads and keeps the reader's attention. It's about how two people who feel an instant attraction discover something wonderful out of their own selfishness. The problem with that is, in real life, we all know some selfishness exists at the same level as most people. One has to take into account how selfish one really is. I also believe everyone wants love regardless where your economic situation is, but it looks like money does not come anywhere near helping out someone in emotional needs.
Example Output: Good Review

Example Input: Another great role for Ford.
