Very pleased with the white plug chime, discreet but efficient, as we understand it well throughout the house and has not deregulated raw weather, such as those we had before.
Perfect operation, automatic synchronization. Solid, forward in time. Distance radio link used: 15m. A red LED lights up on the push button when ringing: useful. Conforming delivery.
Worked from 1 shot (hopefully) ..... ringtones are a little high but somehow it does not help if you want to be sure not to miss a visit / delivery. The tones are a little dated but it does not really matter .... ca is only a bell!
