Review: Would buy again.
Review: It is practical, easy to install and does what it is supposed to. I bought it because I have a two story home with one heating/cooling unit and 2 thermastats and teen kids who kept changing the upstairs. After installing and locking the device, I no longer worry about them changing the temperture.
