LED alarm clock: The projector alarm clock has a snooze function and is equipped with an LED display whose brightness can be adjusted in 6 different levels. Rotating projector: The clock's strike can be projected, for example, onto the bedroom ceiling. You can set where you want the projection thanks to the 180-degree adjustment. Many functions: The alarm clock also has an FM radio with timer function and it displays temperature and humidity. The mirror surface is not only a nice design idea, but also allows you to actually use the clock radio as a mirror. Note: The clock must be connected to a power outlet for full functionality. The battery (CR2032 button cell battery) is only for the clock to continue to display the time, e.g. in case of power failure, but is not sufficient for the clock's other functions.
