“We have been using Rodann products for over 25 years and we love how well the door chimes work and how great technical support has been. There is always a person that you can speak to that is knowledgeable about the Rodman product line. We have over the last 10 years gone from the hard wired AV-100 system to their newest RX1000A and TX1000A wireless door announcing system and have been very happy with the results. They have always been there for us and I will never change. “
