Simple concept: Over time, the colorful disk of the upgraded visual timer disappears counterclockwise. It vividly displays the remaining time and helps users develop a better sense of time and improve time management. No ticking and mute function: Silent countdown operation, ideal for sound-sensitive environments. Three optional alert volumes: mute, low, and loud. Alarm duration options: 3 seconds or 30 seconds. The alert can be stopped by pressing the top pause button. Suitable for many occasions: This 60-minute timer is versatile. 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: Turn the center knob clockwise to adjust the colored disk to the desired time, then the timer starts counting down. The removable silicone shell is made of healthy, non-toxic, and odorless materials, effectively protecting the timer. Low battery and after-sales reminder: If the battery power is low, the light will flash to remind you. Requires 2 AAA batteries (not included).
