Ex Input:
This book was OK although the title kind of leads one to think it's a true story. There are many grammatical errors and missing words (plurals). For example, the term "kitten" should have been "kitt" in paragraph 3 (p. 217). The author does describe his feelings about being able to travel with dogs while he can no longer walk. He explains how he's going to use this experience for others too. At times, it seems as though some phrases or sentences were thrown together hastily.

Ex Output:
Good Review

If you're looking for a water softener to reduce mineral build up in your water, this is the product you want. I have used RO systems before, and there isn't a whole lot difference between them.

I bought this camera and it worked great for about 3 months. Then one day, the screen just says "Error Read Only" or something along those lines. Its a real pain when all of your photos are not able to be saved anymore because you can't download them off of the camera. Luckily i got an extended warranty on it. After sending my brand new camera in (under warranty), they sent me back another one, but with many scratches (and obviously used).

Bad review
