Digital display countdown timer with operation buttons. How about using it for the Pomodoro Technique (25 minutes of focus, 5 minutes of rest)? I think it can be used for the final push for entrance exams. Color: White Brand: Dretec Material: Plastic Product Dimensions: 5 depth x 5.8 width x 8 height cm Product Weight: 78 grams Number of Settings: 1 Equipped with an interval timer function that allows you to set study and break times separately. Repeating study and breaks in a short amount of time is better for maintaining concentration than studying for long periods. The interval timer is recommended not only for studying, but also for managing time for muscle training, workouts, and presentations. Equipped with a count-up function that can measure study time. Ideal for training with the test itself in mind, such as for entrance exams and qualifications. It notifies you with light and sound when the set time is reached, even without looking at the screen. The volume can be switched to mute so it can be used in libraries, study rooms, and at night. The start/stop button is located on the top, making it easy to operate during use. Clock mode to display the current time and alarm settings are also available. Everything in the photos is included. The instruction manual can be viewed and downloaded as a PDF online. Thank you for viewing.
