Interesting Pattern Design: The visual design is ideal for classroom use or kitchen cooking. Practical Ways to Improve Efficiency: Time passage is clearly visible, similar to an hourglass, making it easy to understand for users of all ages. Unlike digital timers, no numbers need to be read—simply glance at the countdown to see remaining time. Extremely Easy to Use: Adjust the time by turning the knob—clockwise to increase, counterclockwise to decrease. To silence the alarm, turn the knob slightly clockwise and then back to zero. Non-Ticking & Adjustable Alarm: Advanced internal construction ensures near-silent operation, allowing focused work without distraction. Alarm volume can be toggled on or off, and ringing duration can be set to 3 seconds or 60 seconds. Suitable for Multiple Occasions: Ideal for classroom, kitchen, beauty routines, yoga, work, exercise, group games, and entertainment time management.
