Took me 2 times to success but finally managed to install it properly. Good thing is that it's quite thick so no scratches. BUT the screen protector is indeed very scratched already in the package. No my phone's screen looks like it's scratched too! Or am I missing something here? Is there another layer that I should ripp off? Don't thinks so.
This rating is only for the paperback version not the text itself. The quality of this version is so horrible that I can not even read it and have to buy the hardcover version. Don't make the same misstake I did!
