After I had been looking for quite a while until I finally got a (supposedly) had found for grade LED ceiling motion, I ordered the MAILUX at Amazon at a top price. The connection is very easy and the settings must be made unkomliziert. The unit turns me 3 LED spotlights with a total of around 11 watts. It turns completely reliable and completely without problems. Each time you switch you can hear clearly that the relay picks up or drops. A deduction of points there, because the retaining springs do not have so much pressure. Depending on how the (usually quite rigid) connection cable to the indicator "drags", it tilted by the device bit in the borehole. For me, but it's not a problem as the cables are loose. I would buy it again at any time.
