However, the - in the truest sense of the word - its price: In a lamp must here at least four batteries. Well, the fact that the lamp is always burning so only briefly, keep the batteries of course already well long! The word in the description "wirelessly", you should replace in my view, by "battery farms".
Knowledge you have here: Description in English only. The drawings are, quite frankly, in my view, very amateurish. I got myself for screwing the lights definitely a screwdriver. Then when spinnig I could see that the material is still relatively inferior also equal. The slots of the plastic screws have but actually totally warped and bent during spinnig with the screwdriver, are frayed. Therefore, it seems, however to very soft plastic.
Hang the lights only once, but everything is okay. The motion does not work for me but all uniform. Since each lamp seems to have a little life of its own. But is okay.
You can screw or stick the lights on the wall. Both works.
The result for me the following conclusion: The lamp can be well install, the light is not too bright, but enough to illuminate a small area. The motion detector works individually, but is okay. The material appears to be relatively cheap plastic, so a star deflects any case the screws deduction.
