[80dB LOUD ALARM]: The kitchen timer emits an 80-decibel alarm that lasts for 3 seconds + 30 milliseconds (tested at a distance of 0.3 meters) when the time is up. You can easily hear this alarm in another room. It's loud and clear, so you never have to worry about overcooking again. [EASY ROTATION]: The mechanical timer requires no batteries, making it energy-efficient and environmentally friendly. This 60-minute cooking timer is designed to control cooking time in the kitchen. Easy to use. So simple that seniors and children can use it easily. [POWERFUL MAGNETIC BACK]: A strong square magnet on the back of the mechanical timer allows you to attach it to the refrigerator, freezer, and other iron surfaces in the kitchen. Ideal for special needs, children, parents, teachers, office workers/professionals, and students. [TWO VERY IMPORTANT STEPS]: Step 1> Before each use, turn the timer knob clockwise a full turn, starting at 0 and ending at 0, until the timer pointer aligns with the zero symbol. Step 2> Turn the timer knob counter-clockwise to the number of minutes you want it to ring. If you do not perform these two steps, the timer will NOT ring.
