Example Input: By something else. This is the worst piece of machinery I have ever bought. Virtually impossible to cut any size tile on the diagonal. Typical imported junk!!!!!
Example Output: Negative

Example Input: Adapter worked flawlessly for six months, then became intermittent. Seems to be broken or shorted somewhere near the connector to the computer. Even the ridiculously flimsy cord from Apple lasted longer than six months, so I can't say I'm pleased. Macally says they'll sell the connector cable separately for $17.00 which is not much of a bargain.
Example Output: Negative

Example Input: I love reading Essence magazine, I am happy I can now read it on my kindle fire. I recommend this
Example Output:
Positive
