So far no problem. They always come to the door but I don't always hear them and if the dogs are out for their walk they can't bark to warn me. But twice now the delivery person knew I was home from the way the door was open so he called me on his cell from the yard, I didn't realize they had our numbers. This is UPS, Fed Ex always come to the door but don't know if they would call me to verify I'm home. Our doorbell wasn't working at the time and we had no clue. Lucky we have a door knocker at least.
