I love the backlit ceiling which gives me the time I open the eyes. It is clean, simple to set up and use. The illumination level 3 position allows to easily sleep well and see the time of day. I like the design and compact effect is handy on a bedside table already loaded. The downside: they announce a gradual awakening. WRONG! This option works only for buzzer but this is not the volume that is progressive: the number of buzz. So anyway disappointed because I made this purchase as a result of this selling point!
