Super fit for a good price.

The fit of the envelope is properly on my iPhone 6. All necessary connections and buttons are easy to reach and operate. The sheet protector does not block the view of the flights, local design of the phone.
Also, the edge on the display side is increased by about 0.5 mm. So you can put the phone sometimes confidently with the display face down on a table without having to worry about scratches.
Remains to be seen whether the envelope yellowed with time. This theme had often in cases this price range. But all is not perfect. Therefore, full marks.
