The timer has a design flaw in that the alarm sound cannot be turned off with a button, as is the case with alarms. To stop the sound, you have to start a new countdown and then pause it. It's annoying. The timer is set to the following times: 3, 5, 15, 30, 45, and 60 minutes. It would be helpful to have the option to change these settings to others or to have product variants with different timings, similar to the German company TFA Dostmann's cube timers.
