Two Timing Modes: Our timer has two different timing modes - silent mode and ringing mode. It is suitable for many situations. Call mode can be used for meetings or lessons. For situations where no ringing is required, silent mode can be used. Adjustable size: The timer has an LED screen, and the numbers displayed on the screen are clear and distinct. The lightweight timer can be carried with you at all times. It is the perfect product for homework, exercise, gym training, cooking, classroom activities. Easy to use: The digital timer clock has three modes (the timing mode is a positive timing mode, a clock mode and an alarm mode). You just need to press the mode button to switch mode. The operation is very simple. Carrying safety: The timer is made of ABS material, which is light and strong. It has some ability to withstand falls, pressure and friction. It can be placed anywhere in the bag. Upgraded magnetic back, retractable vertical hook suspension: The kitchen timer magnet is easy to place in three ways, especially the upgraded powerful magnet works well on the metal surface. Don't worry about the falling problems that often occur with other timers. Because of the display and the shooting environment. Allow some margin of error in color. Thank you for your understanding!
