I got a wireless battery doorbell kit of Byron BY501E delivered for testing. The Funktürklingelset keeps its promises. The ringing is still clearly audible in 125m range. Thanks to the battery operation, the bell can be used without electricity. She has eight different ringtones that you can change to suit your mood. The receiver can be mithinnehmen everywhere, just as the bell if you have not been installed him. Also in case of illness, if you stay in bed and not allowed to stand up, you can ring the bell to call use, as in the hospital. Then you have to take to his bed, however the bell with. Recommended as a second bell for home and garden. I have the bell not yet been assembled because the wireless door chime kit-is then to use Versatile for us. The ringing is audible, so you no longer have to shout and thus protects his voice when you call the family, for example, to eat. From me this bell gets five stars.
