Works according to the price reasonable. One can certainly not expect a sophisticated motion detector, which costs a lot more elsewhere. Light on signaling is quite bright; Melodies are very noisy. 32 melodies well and good, of which unfortunately only 3 pieces typical ringtones. When I look at every time Rudolph or the American style. Will listen anthem when a comes in, I do not need the product, but a psychiatrist ;-) Power consumption of Signalisieres (ie not the motion, particularly the part that comes into the socket) comes to me with 16 Watt remains quite high. Actually must be yes standby mode only in a kind of waiting that the detector is a signal ...
