the parcel arrived quickly, I plugged in (without putting batteries) and it is set to the time after an hour's search. if not impossible to put a time manually. the projection of the hour is good on the ceiling. for now everything is OK. it also gives the temperature of the room, in the future we will see how long it will work. in chala. there are nights it displays incorrectly hours and takes several days to readjust. SUITE: bought in March and now in June, after a break of collective power, it is difficult to put a (time) but with one more hour, and IMPOSSIBLE to set it manually, so that's two weeks that he did not recalibrate and I still have one more hour, that the area has to be a big ..... are what it is because I am next Bezier and far from Frankfurt (the or the signal is sent)
