Hermoso me encantó

I have a 4,000 SQFT warehouse/office. We aren't in our warehouse most of the time but in our office. We can't hear knocks because the office is very far. I put this doorbell in and works like a charm. I put 1 receiver in the main office room and the other in the "smaller" warehouse.Works out of the box. Very strong and sturdy sticker mount.I recommend!
