I am really happy with this case! It is of a good quality, perfect size (I ordered it for Galaxy S5). Back "ribbon" is really useful to take the phone out easily. I would recommend this case to everyone who cares about their device long duration and protection. It would be nice to have even bigger choice of colours :)
This book is really well-written, it has all the essential things you need to learn or refresh in your memory together with good Sage 50 Accounts examples. I would highly recommend it to anyone who wants to learn basic skills quickly.
