Example Input: One of the most comfortable and awesome headsets I've bought up to date. A little in the pricey end but it is absolutely worth every single dollar. A must buy
Example Output: Positive Review

Example Input: While I'm sure it's a good battery for the laptop it fits, the description says it's a replacement for the SQU-720 Gateway battery...not so much. Not even the right size to fit in the battery slot. I suggest updating the items it replaces with a more accurate list.
Example Output: Negative Review

Example Input: Bought 3 units in 2008. Now it's 2015 and all data is gone. I regret having bought this obscure brand.
Example Output:
Negative Review
