Having already been disappointed by the poor performance of other wireless door chimes, I hesitated before ordering the Friedland Libra Home and Garden Kit. However, I was very pleasantly surprised. The Friedland unit is well designed, good looking, and works just as well as the manufacturer claims. There is a pleasant choice of chimes, easily selected. The volume is controllable, from very soft, up to my own preference, very loud. And for the stone deaf the unit also displays a highly visible, unmissable, flashing light. Unlike other units the Friedland really does cover the distance range claimed. Other wireless chimes have failed to cope with our solid brick house and wireless internet interference, but the Friedland's frequency is different to the norm, and seems to work admirably. Last but not least, the setting up was a breeze, even for an old technophobe like me.
