Example Input: We have watched The Rifleman, Buck Rogers and Mission Impossible. All of these shows give us hours of enjoyment. This is even better than when my kids were little! Thanks so much, Amazon.
Example Output: Good Review

Example Input: The sound is good enough and the Bluetooth connected great but after a few months they stopped working. I contacted LG for a replacement which was quick to get here with no hassle. So far so good, however, their claim that their product contains "durable materials" has me doubting my purchase. I've worn them every weekend day while work at an office since December 2013 (maybe 2 hours a day, if that) and today is finally the day when one side died.
Example Output: Bad review

Example Input: Bought 2 for gifts. one has completely crumbled into dust.
Example Output:
Bad review
