For some time I've been sick and tired of replacing batteries on our door bell. You put new ones in and the thing works for a few weeks only to stop again. So now I went hunting for an old-fashioned manual door bell.
I found a solid brass bell which I've now installed at the front door. See how that goes. Oh and I have super-glued all the bolts and screws.
I like it. I just hope we can hear it everywhere in the house.
