This bag is clean and the Lumia 820 fits perfectly into the cup. The plastic is extremely stable, so that the device is fitted tightly and does not pop out even when dropped. The magnetic closure is perfectly adequate. If you do not activate the lock screen, you start ever by mistake one or the other program, which is no shortage of pocket, however, but simply is due to the super sensitive touch screen of the Lumia. Making calls is allerings bit awkward when the phone is in the Tache. If you fold the cover backwards, covered the one additional microphone for ambient noise reduction. The result is that the other party barely hear anything. So when calling the lid does not fold back ... All in all a worthwhile purchase!
