Normal I torture myself up in the morning, without somehow being only half awake, but since I use the alarm clock, I'm awake. Based on the experience I guess that the thing with dawn simulation is good, at least for me. Probably, as in everything, every person reacts not equal to it, but I personally am very pleased that I have this clock now that he obviously does me good.
From the effect aside, I find the alarm clock also very cuddly and very visually appealing, beautiful, I also think that you can easily switch the display at night quite dark, because I was the glow of such displays but often interferes somehow.
Also good, I find that you can be woken up with and without alarm, but you have to say that the sound already gives the impression that he was chosen as a last resort to the final expulsion, otherwise I can not imagine why a should have chosen so ugly tone for it.
However disadvantage is the use of the three keys. After a brief look at the manual, opens up very quickly indeed, how to set the various functions, but I find it a bit fiddly to set the alarm. How often have I now once adjusted the time already in this trial, I do not know but already several times. Here would have been nice if the time would have been set via a separate button. Even that's probably all a matter of practice, but it could just be a lot easier with little effort.
It is nice that you can use this alarm clock as well as a bedside lamp and that not only the possibility to wake up with the sunrise simulator, but also at night to sleep with the sunset simulator.
Overall, I am despite the small criticism of the operation just thrilled and am very happy with this light alarm clock, which I also highly recommend, but you should take a look in the manual for the buttons in any case.
