I would strongly advise against buying this alarm. The presentation of the alarm clock (photo) is misleading, bordering on fraud. You definitely get a different alarm clock! The time is very difficult to read. The display with dark gray characters on gray brown background is just bad. The lighting of the display is insufficient. The alarm can not be read in the dark. Since it is at night looking for the alarm clock. The reception of the radio signal is a gamble. Only after several attempts and respective reset signal has been found. Changing the battery is without aids is not possible. The setting of the alarm time is much too long.
