Ex Input:
The battery died within a week of using the phone. It is not very expensive, but should last longer than that. At least it still holds the charge to hold when plugged into my charger!

Ex Output:
Bad review

I ordered this because of the price and it came with a battery included. My wife was very excited when she got her new cordless phone. It is exactly what we were looking for. No problems at all. Good price,Great product would recommend to anyone.

Good Review


Ex Input:
This book is very difficult to read. It's basically the same thing in a different language. Not helpful. Don't buy it. You're better off buying another book. One of those will be easier to understand, or at least more logical. What I really have trouble with are all typos or errors. The authors must not know much. I've had numerous problems communicating my meaning after using this book, because one sentence makes no sense.

Ex Output:

Bad review
