'Kinetic' doorbells, any good, anyone got one?
In relation to my 'mains doorbells' thread while searching I have come
across 'kinetic' doorbells. The sender/bell-push uses the energy
provided by the user pushing the button to provide power, so there is
no battery in the bell-push. The sounder is a conventional mains
powered device.
It sounds like exactly what I want but I'd like to know if they really
work well before buying one.
