This egg timer is specifically designed for cooking eggs and is incredibly easy to use. The four most important cooking times (3, 5, 7, and 10 minutes) are pre-programmed and printed on the top of the cube. Simply turn the desired time upwards, and the timer starts immediately. The small display rotates with it and shows the countdown time. The red LED light pulses. When the selected time is reached, the LED light blinks, and an alarm sounds to remind you to stop the cooking process. To stop the alarm, the timer is turned to the neutral side. Depending on the situation and your personal preferences, the egg timer offers many adjustable options: the alarm tone can be set to loud or quiet, turned on or completely off. The LED light can also be switched off. If desired, a pre-alarm will announce the end time 10 seconds in advance. Cooking times: 3 minutes: soft, 5 minutes: medium soft, 7 minutes: medium hard, 10 minutes: hard.
