Title: No range, doesn't work through walls
Review: I purchased this because our townhome is situated where our back patio faces the parking so when deliveries come they always go to our back door. The gate to our patio is about 8 feet from the back doors.I initially wanted to place the doorbell near our front doorbell which is mounted in our stairwell between the first and second floors so we could hear it from both up and downstairs. This placement was about 20 feet from the button and the signal would need to pass through our sliding glass door and one wall. It wouldn't work.Second we moved it all the way upstairs to the hallway where it would be closer to the button and the signal would only have to travel through one wall. Still nothing.Finally we put it on the windowsill of the Master Bedroom overlooking the button and it worked. Only now, we can't hear it if we are downstairs. So we ended up putting in on the downstairs windowsill 8 ft from the button and it works.[...]
