La Crosse Technology 919-186-60WH White Cube Timer - 5/15/30/60 Minute Countdown for Kitchen, Classroom & Office Use

This little cube felt like another unnecessary toy when I bought it on impulse. It has turned out to be very handy and much easier than setting the timer on my phone. I can set it for 15 minutes of house cleaning or 1 hour of sewing or 30 minutes to picking up a kid or other little reminders so that time doesn't escape me.
