This "MAILUX flush-mounted movement" could be installed very easily and worked right away. Showing this requires 3 phases where one phase (neutral) can be seen right next to / under the previous switch / outlet especially in a second outlet. The workmanship is very good for this price. The switch for ON / OFF / PIP can be nice move loose. About this switch is a small status LED, which always flashes when the motion "is the scan." However, the LED lights only very weakly, is thus well suited for darker rooms. Under the shutter, the slider for the "duty" and are "light sensitivity". But the panel must first be removed, which also works very easily. Mailux would the motion quietly build a little smaller, so that also for example in "Gira outlet aperture" fits. But otherwise it looks great. Turn he does very quickly and from a distance. I can only recommend!
