Oversized digits on this 20-hour timer let you keep track of its progress from across the room. Use the clearly-marked buttons on the front to set the time by minutes, hours, or both (seconds are not shown), then push start; the flashing colon lets you know the timer is counting down. A pocket clip and magnetic strip on the back add to the timer's convenience. Loud staccato beeps alert you that the time is up; you can either hit the alarm stop button or let it go off automatically after 30 seconds. The extra-large LED display measures 3/4 by 1-3/4 inches, while overall the timer measures a compact 3-1/2 by 2-3/8 by 5/8 inches. CDN covers the digital timer with a five-year warranty against defects. One AAA battery is included for operation.
