Polarity: Positive
Solution is here: True
Explanation: Customer is satisfied with the product. Therefore, it has positive polarity.

Now, solve this: Review: The narrative style of this work by famous founders' biographer John Morse is arrogant, flippant and frequently exaggerated. It carries the tone of the amateur Yankee historian on high, passing judgment on this Southern statesman who was neither from Boston nor a Harvard graduate. Perhaps considered penetrating for its day, it really represents nothing more than opinion today. The research is so thin that one must conclude that Morse wrote the entire manuscript essentially from memory, with little reference to the primary and secondary sources we expect of historians now. If it weren't for the fact that Morse wrote this piece 110 years ago, I'd have rated it only one star.
Polarity: Negative
Solution:
True
