Now the quality
The thickness of the iSaver2 is (I speak generally of a Mac Book Pro Retina 15 inches) ideal. The screen can be closed as usual and the gap between screen and case is identical with and without cloth. In addition, the pad covers the entire keyboard (does not go to the edge of Mac Books) but that it is in my opinion not. The purpose that the keyboard is not to perpetuate on the screen is so fully met.
I use the pad as a mouse pad. Again, I have to say that thus can easily work. The soft material is a boon for mouse hand.
Also good to know: For me as a student, the mat is still very useful in another respect: In the lecture hall, the Mac Book slips often on the small tables down. If one pad with rubber side down on the table and provides the notebook then the pad on it, slips nothing more! My Mac Book stays where it should be!
