As stated in the previous comment, the volume is adjustable, in the sense that when you program your alarm, you set the time, day of the week, if you want radio, buzzer or "nature sounds" and especially the max volume !!! Very important because when you sleep peacefully and that the total calm, too strong volume quickly becomes unpleasant!
The integrated temperature sensor on awakening seems to me not so reliable ... by against the box with the remote sensor is great! In addition, there is a small display above, very convenient ;-) Personally I fixed on my terrace, thus when I'm out, a little look at the display and housing I know how hot it is and on the other side, in the morning I wake up, I threw an eye on the clock display and I know how I have to get dressed to go out.
The use is not complicated but it is not super intuitive either, take the manual with you when you plug the clock for the first time, it will surely be useful ;-)
The digital FM tuner is great, my old clock radio was still equipped with a wheel, barely éfleurée, the radio station was wanton and sound that came out was becoming unbearable!
Another thing is the intensity of the display (blue display, beautiful and relaxing for both eyes and with large numbers), I would say that level of intensity, you have "very low" , "strong" and "strong +".
Very low: you see nothing during the day, it looks like the clock is disconnected but at night it's nickel, you open one eye to see the time and you are not blinded by a display that strips you retinal!
Strong: Well ... hard, that's all I can say, the day you see everything on display but at night it lights up the room too.
Fort +: Is this necessary?!?
There are 2 separate alarms, handy if you want to use an alarm clock to 2.
There is a lithium battery in the wake of this, if there is a power failure, the time remains set correctly and you do not risk a failure alarm in the morning.
Anyway for me it is the top!
