I have a battery-operated alarm clock wanted that one also can read at night. He has it apparently a light sensor that easily turns on the backlight when it is dark, so it does not interfere, but you can see the large-read time. On touching the top of the display for a few seconds is really bright. Unfortunately the picture entsprciht here not the model supplied. It has no buttons but above a berührungsempfindlche area (but also looks good). For the money the unit is ok. For comparison - I have previously bought a teuen Braun alarm clock. I can read at night but only at a keystroke - so I can not do anything.
Disadvantage: The usage may be easy and you do not need manual (which is not already there) - but a German or English lettering would be good. With Chinese or Japanese lettering on the back, I can not do anything. I will complain about that. Therefore only used *** - stars.
