The instrument should serve as a simple, robostes device for my father. Since he does not attach importance to the technical bells and whistles such as high resolution camera, etc., this device of price and performance was absolutely great! So ordered, unpacked, set up, everything was great. But after a short time the handset and the microphone was no longer. Only if one of the "talking loudly" button pressed, my father heard me and I him. Cause: it had fallen out of his pants on the carpeted floor. Ok, still under warranty; So back to the device. Get a new device and re-established everything. 3 weeks later the same game. Again, the device had fallen on the carpet. Calls again impossible. So returned appliance final and opted for the Moto G. Since then no more problems.
