Ex Input:
This book was written in the 70's by a man who knows his stuff, which is a rare find nowadays. The problem with it is that he relies too much on anecdotal stories and anecdotical sources to support his hypothesis. It feels like reading someone's blog, not science. Also, some of the anecdotes don't make any sense unless you can explain away how they happened.

Ex Output:
Good Review

The sound is good enough and the Bluetooth connected great but after a few months they stopped working. I contacted LG for a replacement which was quick to get here with no hassle. So far so good, however, their claim that their product contains "durable materials" has me doubting my purchase. I've worn them every weekend day while work at an office since December 2013 (maybe 2 hours a day, if that) and today is finally the day when one side died.

Ex Output:
Bad review

I am disappointed I cannot find these cartridges on the shelf at any of my other local stores. It shows a generic cartridge, so I can not judge what this one is, and how good it is. This review has no influence on whether someone will purchase it, but rather why they are showing the photo as shown. The cartridge seems to work, except for two things:1. Not all 3 colors worked. There were only 2 left in each color cartridge.2. Only black printed clearly.
