The timer is very easy to use. The alarm is loud enough - even in large spaces such as auditoriums. Disadvantage: the acknowledgment in the setting is just as loud. Since I as a timer at Eigungsdiagnostischen test that must be processed on time, may establish the unit, scaring the participants in setting often, or think of Tastquittungston is the starting signal to get going. Nevertheless, for that purpose an excellent device. Especially with long processing times of 10, 20 or more minutes allows the device to solve his eyes off the stopwatch and meanwhile to deal with other things without losing sight of the time. It is also much louder than a sports stopwatch.
