I have long rumüberlegt which Lichtwecker I should nehem, I have read many reviews and am then come to this, because the brand is generally very good rated and the pioneer of all Lichtwecker seems. The Body Clock Alarm Clock by Lumie alone speaks to its quality for absolute in itself. The material and the structure are stable and reliable. Although he has only three buttons on the operation it is easy to program the desired functions. These are of course the time in 24h, the alarm time and the alarm. The light brightens over the specified 30min evenly and then remains still for a while before it goes out. So what does arouse the company in terms of light made their task well. What, however, is in need of improvement, on the one hand is the display. This work itself properly, their light goes out completely when the alarm is set, so does not interfere with sleep and can be illuminated by pressing a button for a few seconds. If the alarm is turned off, however, because you want to sleep, the display remains lit and you have to turn the alarm if it bothers. Another, however, very little noise factor is heat generation while increasing brightness. The lamp so you should perhaps not right next to the face have because it is hot in the long run. However, the worst aspect of this alarm is the alarm tone. The proceeds not in my opinion. The one hand, gentle Waking up to the light is made by this beep completely destroyed. He beeps not even normal but sounds like he die painfully. It is now square to the bed, this beep is clearly too flashy and not gently, like me, the manufacturer in an e-mail matrimonial assured. I am therefore again switched to my original clock, which at this price therefore is not quite ideal. But his main task is fulfilled the alarm clock very well what is the most important thing and so I am pleased with him.
