Visually, it is a very handsome shell, actually just the right for the Lumia 925th Unfortunately, the reception signal my phone attenuates extreme. I usually only one bar reception when the device is in the envelope, 3G or even LTE are therefore not to be used only. I do not understand what it is exactly, but I have only this envelope. Have they had already ordered 2x. As soon as I take my phone out of the envelope, I have again used strong signal with my old shell (of rock). This symptom with this envelope is reproducible at any time. I am T-Mobile customer. I suspect that the "dog teeth" aluminum etc. and are associated with the aluminum frame of the Lumia 925 leading to disturbances.
Processing and optics of the shell are great.
It is only to be noted that the corners of the equipment are not protected as it is usual with cases.
