The lamp works very well. Especially movements are very well recognized and Leuchkraft is excellent (so really very bright). I bought them for the caravan, because not all are light switches and so you do not have to look long in the dark. Only improvement is the switch: Well it would be if one of "on / off" (ie manually) a right switch (and no slide switch, which is difficult to adjust) would. But if you only use the motion detection feature that's fine. And for this price that's fine too. Therefore 5 stars.
