To clock yourself:
He has the most important functions, and most importantly, the transformer hums not, the device makes no noise, and even the beeping of the sensor can be switched off - super!
The setting was amazingly good, mostly even without a manual, if you had already similar devices. Wakes me from the radio, which is totally ok in volume. High demands on the sound quality I have not, he would not keep. But at least it is to get noiseless by the digital tuning. Another advantage is that you do not accidentally while cleaning the volume adjusted, as was the case with my old alarm clock.
The display is in the darkest setting in my opinion still too bright, but here there are two ways to remedy the situation:
1) turn off the display completely (if you want to know at night, what time it is, just wag over the sensor, it displays the time for a short time on)
2.) If you want to have always displayed the time, help a film that is also used for darkening the car window. Then the clock is indeed impossible to read in bright rooms, but I do not need. The projection I've turned off.
A disadvantage is that the alarm clock has a somewhat unusual feature that you can activate by mistake: the short-term alarm. Thus one can be with one touch within 10 to 90 minutes again be awakened. I'm just guessing, mask off this function directly! On the first night I was awakened twice by 90 min, until I searched the manual unnerved because I had pressed the button on the alarm setting by mistake!
Because of these two issues, there is of me only 4 stars.
