Title: Units communicate poorly with each other
Review: After some difficulty in programming three of these they worked properly placed several feet from each other. However, they failed to talk to one another even in direct line of sight when they were more than 30' apart. And so they were useless when one unit was put in the basement and the other two located in upstairs second floor bedrooms. So a cautionary note to the buyer; try them out at once and be prepared to return them promptly if they don't communicate properly in your installation. I waited nearly three months to install them and now I may not be able to return them.
