This small digital visual timer allows you to set the duration anywhere between 1 to 90 minutes. Once set, the entire disk will represent the duration you choose! A magnetic back makes the TWIST® a snap to display. Easily attach it to metallic surfaces from refrigerators and file cabinets to the whiteboard in your classroom, kitchen, or home. To use, simply turn the outer ring until you get to your desired time, then push the play button. Unlike our other Time Timer visual timers, the Time Timer TWIST® has a continuous alert at the end of the duration to ensure you don't miss it. The alert can be stopped by pressing the Play/Pause button, or will stop after 1 minute of beeping. Need to take a break half way through your timed event? Pause your timer during the countdown by pressing the play/pause button. Countdown will continue where you left off by pressing the play/pause button again.
