Example Input: These things feel very flimsy and thin. The plastic feels almost disposable in comparison. I have only had them for 6 months and already one ear bud is not even working. I've never used the buds at excessive volumes but when it comes right down to it, they just don't last. It would take me a few weeks tops before these were no good, let alone 2 months. It's too bad because i really liked them.
Example Output: Bad review

Example Input: This is a very high quality dog food and I found the price by far higher on this one than in stores. Dogs love it, but they are more active when giving it them. It cost me $4.56 per bag here at Amazon, which isn't bad, so even with shipping there may be an incentive for you to try it. It came quickly as usual, just wish Amazon would lower their pricing! Thanks again. Jim W - Arizona USA
Example Output: Good Review

Example Input: I would agree that this author was a little off the mark, but not by much. The plot of the book could have been an interesting story had it gone deeper, with more mystery to it. Instead we get a very standard spy story with cliches and one dimensional villains. And some really odd characters thrown in for good measure. If you're trying to develop your skills at espionage or if you want quick action without losing too much brain power, then this is your book. Otherwise, look elsewhere.
Example Output:
Bad review
