Ex Input:
Not what I was hoping for. Wish the information had been more clear about how to clean it properly and such. Didn't even get through half of the book. Maybe I'll give that one a try someday! The pictures were great though.

Ex Output:
Bad review


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:
The title doesn't really reflect the contents. There wasn't much of a book to get you started, in my opinion. You would probably only need this guide if you're going out on your own and don't know how it's done. If you have already purchased their other books, by all means, read this, but be prepared for even fewer ideas. It is good that there's more space devoted to getting started - there isn't too much. I'm just disappointed it didn't live up to my expectations.
