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 Input:
There are some nice ideas and the recipes sound good, but for my first attempt I'm still looking for an easy cake cookbook to cook without a mixer. I tried two recipes that turned out very well, so maybe it is me who needs help. Not worth what seems like quite an investment. Sorry.
