I know this has nothing to do with electrical wiring, but I couldn't think of a better forum. What do actual electricians recommend when someone wants a wireless doorbell? I would love a brand and model number recommendation. I have purchased 3 over the years and none of them work or they ring when nobody is at the door or they work for a while and then stop working or they won't ring when the door is closed. I want one that rings. It's not asking too much I don't think.
