The numeric keys are indeed passebel and the overall concept of the phone is actually very well done (sound, service, design, etc.). But unfortunately, unfortunately, are two of the most important and most frequently used control keys - namely the two black, rubberized buttons at the bottom of the black upper part, the "OK" and "Back", and other important functions zuständing are for - made extremely cheap! If you press there, knarscht the housing, "stick" the keys lightly on the edges of the housing section (both when printing and when it is released) and do not have a solid tactile feedback. They are "vague" and offer a total of the feel of a cheap plastic toy. Completely out of the question for me, and the (only!) Reason why I return the device, looking me otherwise.
