Ultra-clear LED display with 2 brightness levels. The screen will automatically turn off if there is no operation within 5 seconds, saving you the worry that you may forget to turn it off manually. NOTE: It is highly suggested to set it to ECO to extend the battery life 3 adjustable volume levels: the loud alarm (80-90dB) is very easy to hear even when you are away, soft volume (60-75dB) is much better when used by children to protect their hearing. A mute level (digits flash) is added for quite high demand (the alarm will also beep while setting in high/low volume mode, please set it to mute level as you need) Countdown and Countdown Time Management: Countdown from 99 minutes 59 seconds to zero, or as a stopwatch counting from 0 to 99:59, makes it a perfect timer for housewives, kids, teachers, students, cooking, skincare, yoga, gaming, meetings and classrooms. Place the timer where you need it: two powerful built-in magnets coated with silicone for strong suction and no slip, easy to stick it on any metal surface directly, or you can hang it anywhere using the hook, it also comes with a stand for the place on desktop Super easy to use with big buttons: separate M and S button to set the exact time you need, SP/ST button to start/pause, CLEAR button is added to facilitate resetting. When the countdown ends, you can press any button on the top to recall the last time setting, saving your time to set it again.
