Simple Concept: As time passes, the colored disc on Yunbao's upgraded visual timer disappears counter-clockwise, clearly showing the remaining time and helping people develop a good sense of time and improve their time management skills. No Ticking & Silent Function: The visual countdown operates silently without ticking, making it ideal for noise-sensitive environments. 3 alarm volumes are optional: silent, low, high; alarm duration: 3 seconds/30 seconds. Press the top pause button to stop the alarm. Suitable for Multiple Occasions: This 60-minute timer is a versatile timer. It can be used as a cooking timer in the kitchen, a study timer for children, a task timer for teachers in the classroom, or a meeting timer. Easy to Use: After turning the central knob clockwise, the colored disc can be adjusted to the desired time, and then the timer begins to count down. The silicone cover is made of healthy materials, non-toxic and odorless, effectively protecting the timer. Low Battery Reminder: If the battery is low, the indicator light will flash to remind you. 2 AAA batteries are required but not included.
