One of the switches works well. The second one allows you to turn off if the first one has been turned on but does not turn on again although the receiver signal flashes. More than buying another brand. We understand the price.
Nothing could be simpler to install. I installed it in a bedroom to create a back and forth between the entrance and the bedside. Place and connect the 4 wires at the ceiling lamp, close with the half-sphere cover then stick the two wires to the wall in the desired location.
