The alarm clock does what he is - shows the precise Uhrezeit, wakes reliably and with the large button on top for lighting at night, he is also quite handy. But here lies the great and only drawback for me: to the slider for the activation and deactivation of the alarm to activate, you have the alarm hold (it is not very stable and because the slide at the front, is the alarm clock without falling By contrast, hold). If you try this with one hand, you can always come here to the illumination button on the top and switched the light on unintentionally. I think that's terribly annoying!
