I am sooo disappointed. I was excited to receive the unit and to finally get it set up. I wanted to give a 5 but I can't. The unit is smaller than it looks and sits on the floor versus the couple of inches shown in the picture. I had it installed by the Handy Installer. When he finished, the lights did not work. He did everything to make sure he set it up correctly. We took the remote to have the battery checked and to see if it was actually transmitting. All aspects checked out. I give this a 2 because they are sending me a new unit but I will have to make sure I am home, again, for the person to come back an install.
