This is a great little device! We have a gated entrance to our porch, people used to have a hard time reaching our doorbell through metal gates, now they press it easily! It has been working without problems for almost a year, the battery in the call button works perfectly. We only use one bell for our 1800 square foot home and we don't think another bell will be needed. We thought we could put her somewhere outside if we were in the backyard, but didn't find a place where she would be safe. from the weather. Edit: Added photo, we need to repaint our security gates, but black still fits pretty well :) Update: almost 2 years since our purchase and the original batteries finally let us down, not too bad
