The cover is from the inside and outside without a coat. This means that the resulting classymatt acting surface quickly attracts dust and is then dry not to clean. Under running water cleaning is but done in seconds.
The cover fits well, is easy to pull on the unit and has for the camera, the NC-mic on the back and all connections recesses. Even the edge of the glass is enclosed, the LCD remains completely free. The speaker bottom of the device (from the ringtones come) but is not open. This ringing / Handsfree / Music is naturally quieter. On the long sides, the shell does not sit very firmly. It would be desirable at the point that it sits slightly firmer, but it does not look easy, so only notice when it touches there.
With the shell matter of protection is considerably improved against falls! From a height of 2m onto the concrete floor my DEFY has survived several falls with no apparent damage. Of course, nevertheless, a sharp stone damage on the ground and the display of even greater height is certainly the DEFY itself sometime be somewhat damaged. But this protection should be significantly better than it hinbekommt the unit without cover against accidentally falling from the usual ups.
Of course, this envelope carries on. But that's the price of a good protection; thinner shells protect less well! The sheath is also non-slip; This means that a device not easily slip away, but it's not so easy to get out of the jacket or trouser pocket.
CONCLUSION:
A good protection against impact damage to the phone if you often work outdoors. Not necessarily very pretty and dirty relatively easy. Unfortunately, a cutout for the speaker is absent. When it comes to protection is primarily a good choice!
