I bought this motion for the cellar and am very happy with it! The installation was very simple and straightforward even for hobby electricians as I am a very suitable. Have to be ordered before another motion for the remaining premises. 09/11/2014 ... life unfortunately only 1 year, the unit has started to turn on the light whenever it felt like it. Now switch on the light no longer and therefore I removed the motion and also complained because the warranty anyway lasts two years, unfortunately without success. Will therefore be ordered from this dealer no more products! Too Bad !!
