We've been in our bungalow for a little over 5 years and during this time we have despaired over the number of battery doorbells we've had pack up on us.
So, we decided to bite the bullet and put a wired doorbell in so there's no "interruption" between the bell push and the ringer thing you have indoors. (I don't know the proper name for that bit - sorry!).
Internet research duly started. We were amazed when reading reviews at the amount of bells that "although it dinged, it didn't dong" and "the bell didn't go dong".
Personally I prefer a more melodic doorbell but we now have one that - hopefully will "ding" as well as "dong"!
Any of you got one of those bells where it sounds like you have a ferocious dog indoors?
