## Description

Review: Electrical connectors worked with old models. - Plugged right into the 15+ year old ceiling mounts. Work perfectly. You can even program a room name to each unit. The only critiques is that it would be nice to more room names to choose from (for instance it would great to have primary, secondary, tertiary etc.. bedroom names, also living room, family room).
Review: Good product. - Quick delivery. Connected to my old unit nicely.
