Review on Runleader Countdown Replaceable Reminder，Use Classroom by Kristin Rogness

Great timer. I regularly run 4 at a time. They are stored in memory. When the time is up, the buzzer will turn off (if desired) and the time will start counting down. The screen will indicate if it worked once or multiple times and you missed it. The buzzer is loud, medium or off. The volume is more than sufficient. The screen does not turn off. The ONLY negative is the viewing angle. To reset the timer it must be stopped, then it can be reset. The timer can only be set if you delete it first. It's great for running timers at the same time, e.g. B. a 24 hour timer for your medication and then a 5 minute timer for the oven.
