Especially in current times, hygiene is particularly important. Proper handwashing needs to be learned to effectively remove all bacteria, viruses, and germs. Keep hands under water, lather all areas for 20 seconds, rinse off the soap, and dry hands. This timer not only helps children adhere to the recommended time, ensuring their hands are thoroughly clean. Simply activate the timer with the large button, and the time starts counting down while the large LED light shines red. When the recommended time of 20 seconds is up, it turns green. The timer can also be used for tooth brushing, with a preset brushing time of 2 minutes. After 60 seconds, the red light blinks three times, indicating that half of the time has passed. A wall mount is included for easy installation with adhesive tape (included). Ideal for nurseries, kindergartens, after-school programs, primary schools, medical practices, and families with young children. Batteries 3 x 1.5 V AAA are not included.
