The shipment went as always fast. When installing then but disillusionment: no screw clamps are located on the dimmer for installation in the can. Only cans of recent construction with screw devices are so easy to komibinieren with this dimmer. As a way out, I had to put two small plugs beside the can and then attach the dimmer, an ugly detour. The wiring of the dimmer was not a problem with two small screws, the cables are attached. The actual dimming function worked perfectly, with me flickers nothing (did however Osram LEDs installed). Only the minimum I had to adjust, but was not a problem. Each time you switch you get the feeling that the plastic abkann not too much, because then you realize the price-related processing. For the price of the dimmer is but ok.
