I reluctantly replaced it with another wireless one - this time the most
expensive one that I could find in stock locally - a friedland EVO 200 or
something like that. Has been excellent and totally problem free. And is
has CD quality (well, they claim that ) saxiphone tones ;-)

I got 3 of these Friedland wireless bells, and would only give them 8/10.
The batteries run out quite quickly
(I use rechargeables, and they last about a fortnight).
It only rings once, when the bell-push is pressed;
and the sound is not very loud.

You can change the frequency in use,
so I don't think there would be any problem with interference.
(We didn't have any, anyway, and we use cordless phones.)

They are well-made, and quite neat.
We use the system that extends a traditional bell,
so the ordinary bell rings too.
(I thought the plastic bell-push was a bit tacky.)
