Extremely emfehlenswert!

That this case replaces the phone back wall, not only saves weight, but makes the phone in the envelope also extremely slim.

That you can operate the phone through the viewing window, is great. The integrated S-view screen is a nice feature. However, one must note that the photos that you do in Case closed, have a different format. They are square, such as the clear window of the envelope. Taking this but noted this size difference can be quite used selectively.

Overall, I am - also with regard to the fit and finish quality - very satisfied.
