Example Output: Good Review

Example Input: I purchased the product and did not use it for a few months. Finally gave in to having my carpets cleaned. Today I went over with this steam cleaner and guess what? It just got so hot that there was no way I can vacuum any further. There is condensation on all of the brushes because they stopped turning. The carpet looks like crap now. DO NOT BUY!!! Just spend another $2000 up front and enjoy your new machine.
Example Output:
Bad review
