The same applies to the holding device for the mobile phone, or what it should be time. This simply consists namely of a rubber-like coating which is attached to the inside of the sheath.
If you have a mobile phone released only a couple of times "Attached" and again is the adhesion of the coating away unfortunately there's always a little bit of dust or dirt with it comes. Can cleaning the coating is unfortunately not.
Since it can unfortunately also quickly pass times that when you open the envelope a counter sliding the phone, or even fall off.
In my view, a clear Fehlkonstruktion! Because with such a product a certain attention should fall to the secure hold of the mobile phone part of the manufacturer yet. But what unfortunately is not the case.
I assume that the majority of mobile phone users do not want to scrape off the floor broken his device, so I can only advise against the purchase of this envelope!
