Example Input: I bought this charger thinking that it would be compatible with my late 2005 iBook G4. The description page has nothing stating that it is not for ibook G4 but only for Powerbook G4 and ibook G3. Also, after only about 3 weeks of use the charger died completely. This is by far the worst charger I have ever had. Pros: quick ship Cons: incorrect description, lack of durability
Example Output: Negative

Example Input: I wouldn't recommend this book to an enemy. True, the information may be worthy, but the writing style and the narration were horrible. It is definitely NOT written (nor read) in a conversational manner. I'm willing to cut the narrator some slack as he was only reading what was written, however better inflection, phrasing, pauses, etc... would have greatly helped this otherwise tedious book.I couldn't even finish it. I suffered through the first 5 disks and after all that investment in time I couldn't bring myself to listen to the 6th. Its just that poorly written.I'll restate the fact that the message -- the information -- is worth hearing, its simply written in such a tedious manner that I couldn't stand to hear it through the end.I think I'll donate it to my local library.
Example Output: Negative

Example Input: To me this book would turn a young person, like my self away from the key and enjoyment of reading . Being a book with extensive mistakes in it, it is very difficult to read unless you are to inerpret it every paragraph or should I say sentence. I't maybe a classic, but I feel that the word "classic" comes from just being old........................................................................................................p.s the only reason I put a star was because I had to, to express my opinion on he novel.
Example Output:
Negative
