Why only three stars?!?
Once the batteries are no longer completely full there is a problem with the sensor.
This then goes on constantly, which would not be so dramatic but merely annoying.
BUT !!!
When the sensor alarm is then immediately and automatically switches off the alarm.
That is, it will beep once (!!!) shortly. A star deduction for it.
This is of course far too little to someone at 5.00 clock in the morning from the REM sleep phase to pick up. For me at least.
Unfortunately, the clock does not display how full the battery or if it is almost empty, other alarm in cheaper classes have this feature already. Battery symbol u. Ä.
Another star deduction for it.
Thus, it is a "ticking time bomb" that makes a regularly overslept. Whether the boss participates in the long run?
