Digital Alarm Clocks
In a bedroom or guest room the display is the complaint, not the alarm: a bright unadjustable readout lights the whole room and gets turned to the wall. Look for dimming. Battery backup is the other practical feature, since a mains-only clock loses both the time and the alarm in an outage and nobody notices until morning. Dual alarms suit shared rooms.
