Sounds like a good idea at first, it goes from day to night at a scheduled time. But it works with older bulbs (no LED) slamming very quickly. It works on the sector, and each disconnection caused him to lose memory, worse, it generates a small voltage that makes the HS alarm. He has already made a return to service, then the problem started again. Now the display is barely visible. In short for the price, I find this very bad awakening, very disappointed.
