Ex Input:
This book is a collection of two books, so you basically get the first half for free and have to buy the second one because they are not in order. This makes me quite angry. It should be stated immediately that this isn't just an inconvenience. For example, if I want to know some information about how to implement data encryption with Mailvelope, I'll look it up online using [...] first, then try again by finding the URL with mailvelope.com/learn? And that's it.

Ex Output:
Bad review


Ex Input:
I have had this case for about a week now and it looked beautiful when new. But the design has rubbed off in lots of different places including where you open the stand. It looks terrible now. Also, once i snapped my phone into place as usual, even with only minor movement, not one but both parts came apart from each other.

Ex Output:
Bad review


Ex Input:
This is as good book if you are reading on Kindle. It allows the reader to follow both stories at same time and also leaves it up to you not have problems with switching between stories,which often happens when someone wants different chapters in a single book. However, I would appreciate being given more information about certain characters or events before starting a story.

Ex Output:

Good Review
