    As far as functionality and use these are great. The only reason it is getting two stars instead of 5 is because during my rough electrical inspection I was told that these violate the NEC. You cannot by code have a device like this hidden behind the ceiling. I am being forced to put in a 8X10 access panel in the ceiling to get to it for later use. You can avoid this by getting the model that mounts in the box. They call this a retrofit box but it costs 4 times as much.

    Where were these when I remodeled my other house? What a great device. Way better than fighting with jamb mounted switches. Just buy 7358 - Long Round Magnetic Contacts and it works like a charm.

    Worked as advertised. Very pleased.
