Input: Consider Input: Bought this set based on low price and good reviews. Works fine for poking logs occasionally and cleaning up when stove is cold, but while using the shovel in the fire, the black coating started bubbling, then caught fire.

Output: Negative

Input: Consider Input: I am a country and western fan in Memphis. This new Sony product is great! I meam really great. I don't have to remember songs I hear on the radio anymore. Definitely worth the $19.99 I paid. Get one!

Output: Positive

Input: Consider Input: I had a wonderful time reading the book (and taking notes). It reminded me of the multiple occasions in which I have failed for lack of skills, but also showed me that there is a methodology to follow next time I have to confront a violated expectation (probably within the next five minutes)
Output: Positive
