Very thin shell that is hardly noticeable

Addendum 01.07.2015:
Yesterday it happened to me and the iPhone is the light switch heritage workers fell down from approximately 1.20 m and they go directly to the lower corner on natural stone tiles.
The shell is broken on the corner, but the iPhone has survived the accident unscathed. * Thumbs up *

The shell is really super thin and fit (iPhone 6 Plus) is also very good.
In some places Plastikgrate are felt, but which can be ground off with fine sandpaper - for the price I can overlook this beauty quirks. To the complainers: The Case for 30 euros or more are not much better processed ...
For Protection:
The back and sides incl. The rounded corners are enclosed and are thus protected from scratches. The lower side (Dock Connector, Speaker and Headphone socket) is open. The openings for the switch (mute, volume up / down and power button) are cut precisely and the buttons / switches reached very well and operated.
The back camera looks despite envelope estimated 0,1-0,2mm forth, but the display is not on the table because the envelope a few 0, x mm projecting at the edges.
I think it should be clear to everyone who has a little knowledge of physics that these very thin shell damage to the phone from a fall of more than 1m can not completely prevent.
It protects against Kartzer certainly in everyday use, taking into account not thick on.
All others who often throw down their Smarphones times without damage should better buy an envelope, which have min. 2mm material thickness ;-)
