This timer is very suitable for use in the field as it is easy to use with just a press of a button, and the time can be entered arbitrarily because it has set the time that is commonly used in restaurants or cafes. In particular, after the timer is completed, a voice message indicating that the timer has ended appears, so it is okay to operate the timer and do other tasks. Another useful feature is the ability to take notes, so you can take notes right away on the spot and recall them when needed.
