Example Input: When used in conjunction with a new water filter i no longer have to replace my Brita when we change filters. Very easy and fast to get the water flowing. You can switch them out more then once.
Example Output: Good Review

Example Input: I'm disappointed with this one. I really enjoyed her other books. This one seems disjointed and just doesn't go anywhere. At least the plot itself is interesting. I'd rather read a book in which she explores the human psyche. It's so easy to tell us something interesting about what makes people tick that it's very difficult for me at times to get engaged or invested in the characters. There's too much repetition of character actions - they say exactly the thing we're expecting them to do then act totally different.
Example Output: Bad review

Example Input: We purchased three batteries to replace a previous ones from HP on our dv9000 series Pavilion laptop. After charging these new batteries, we put them in just as the old one, charged and they worked GREAT. These "new" ones, however, are junk.
Example Output:
Bad review
