The cover is easily installed without leading their mission absurdity because arise during installation scratches on the phone, especially when one is more common takes out. On the other hand it is kept stable without that one would have to worry that one slips the phone from the case. The cutouts for the camera and switches are placed precisely. Thus, the functionality of mobile phones is restricted in any way. As the title suggests, mumbi Cover fits the Smartphone incl. In the Bugatti slim case.
