It's exactly as described and works great. Very good for the money. The suction cup is also excellent. Don't hesitate to buy.

Good 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:
i am really shocked that this book made it to print. there is not one thing in here worth taking the time to read. save your money and get something by a real scientist. most of what she writes about are just wrong or misleading. her writing style leaves so much to be desired. I was forced to give this at least 1 star because amazon would not, which says alot more than i can say. if you were thinking bout buying this, don't. buy any other science book.

Ex Output:

Bad review
