- Easy to use and Intelligent battery saving: With just a twist of the silver knob on the black body, you can easily set the time and start or stop the timer. This one-button operation is so simple that even elderly grandparents and young kids can use it. Plus, the digital light goes off after 5 seconds and the device shuts down after another 5 seconds to help save battery life. - Magnetic & Time management: With two magnets on the back, you can stick this timer to various surfaces such as a classroom whiteboard, a cooker, a student's tablet, an iron wall, a fridge, a sports gym, or any other steel places. It's perfect for helping students focus on their studies, time management in the shower, during games, teacher organization in the classroom, mothers cooking and baking, egg boiling, and helps those with Autism ADHD ease transitions and encourages independence and productivity for all abilities. - Large LED Display and Continuous Bright Function: The 3-inch large digital numbers and continuous bright function make it easy to read at a long distance, even in large meeting rooms, classrooms, big kitchens, or exercise rooms. - Loud Alarm and Digits Blink function: There are 3 levels of alarm sound mode (quiet, normal, or up to 90db) and it doesn't beep unnecessarily when you're setting the timer. You can hear it in another room, and the blink-led digital number will remind you when the time is up when it's on Silent mode. Say goodbye to worries about overcooking!
