For cons, I want to reiterate something to all those who are unable to use buttons: the "sensor" (that is to say, the automatic lighting of awakening when the light is low so the night for example) MAY BE OFF! At the back of the clock, there are all the buttons for setting the time, date and alarm, and .... A button named "sensor" that can be positioned to on or off. And for that revival is not lit at night simply put to off, nothing complicated even without knowledge of English. I even say whether it has already been said because of the opinions of all colors of this awakening, there are too many complaints about it.
The settings are simple and intuitive, I did not need the manual.
Negative: I find it a little too big revival, but it's my fault I had not looked at the dimensions. That said, you get used very quickly.
