With this experience, I bought me this bag for my new phone. Even when you insert the phone, I've noticed that the inner shell is made of plastic other than that of the old pocket. The insertion was quite difficult, because the plastic is extremely hard and inflexible. And probably very brittle, as has been pointed out after only a few days use. Having the first time set the vibrating alert, characterized the upper right corner is also equal chipped and a very sharp edge arose.
I was glad when I had the phone off this crap thing out again, without damaging the upper edge painted!
Meanwhile another, identical Mumbi bag for a Huawei has shown in the same Relatives fatigue, after also only a short useful life, without any falls. Chipped a corner and in addition, cracks in the shell.
Here you have probably selected a completely unsuitable material because of the price. No comparison to my old shell!
What I also still aufgefalllen: The surface of the old shell was also leatherette interior, as the outside. Here holds the bonded inner shell properly. Since I now eh no longer use the old shell and me resending is too stupid, I once tested the durability here. Conclusion: the top layer of the inside is easily ripped out at low load, since even the best adhesive will not help.
Too bad, really bad. My old bag was perfect, this one with the hard and brittle plastic and the "paper inner surface" is not worth the money. Who really wants to "protect" his smartphone with a bag, which I can only strongly advise against this bag!
EDIT 04/28/15:
It was probably not just me with the broken plastic cup. Mumbi has apparently called all customers who have ordered this bag lately and asks if you are satisfied with it. I have the really friendly staff described my experiences, after which they sent me a replacement bag, in which the issue should no longer occur.
At this point I must say that I was surprised really positively by the call. First-class service!
I raise now time to 3 star and will test the new bag.
