[EX Q]: 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 A]: Bad review

[EX Q]: We never received this item. It was shipped one way, then sent via carrier pigeon. Very disappointed! Did not bother returning.

[EX Q]: My dog won't use them... They are so hard and not at all worth the cost.... I would never purchase this brand again. It did ship quickly though. Oh well. I will give them to somebody who has a small dog. Very disappointed!
