Title: Microphone not consistent, then failed
Review: This doorbell extender works by placing a small microphone near your doorbell. The microphone listens for any loud sound within a certain pitch range, and then triggers the remove units, (which plug into outlets.) While the remote units were loud and worked great, the microphone on the main unit was very touchy. A loud yawn would be enough to set it off, but many time the sound of the doorbell ringing would not.After about a year of ownership, the chimes started getting set off for no reason at all, and about a week later the microphone stopped working all together. I'm now stuck shopping for not only a new doorbell extender, but I need new satalite units as well, meaning that this will code me at least $40 to replace.
