So boring, I know - they all seem to die from the rain (yes, really!) but my porch door self locks, so no one can access door knocker on front door, & door knocker not a possibility on glass porch door. The only one that lasted for a few years was from Tchibo, but they don't exist in the UK & change their offering a la Lidl every fortnight anyway.
Any recommendations for a longlasting doorbell. Can't wire one in for longwinded reasons.
