Very good equipment at reasonable price: 52 melodies bell!

In the countryside, with a good distance between the gate and the front door (50 meters), this kit wireless doorbell Etekcity is ideal. It consists of a doorbell button transmitter with its battery and its fasteners (screws or tape) of a receiver to connect to power supply and a second receiver that works with 3 AAA batteries not included.

The performances on the paper are there. Indeed, despite the distance and the walls, the bell well control the receiver plugged into the house and the nomadic receiver. It has 52 melodies a bit tedious to go through and the volume is adjustable.
Little more, to get notified discreetly, a blue light flashes on the receiver.
