I use it for timing in scent work trials. It does great. I like the intermittent time warnings. It gives a warning beep at :30 and as the beeps progress so the intensity of the beeps. It also counts up past your target countdown time. One big feature for me is the time does not go away. Some of the other timers the face would black out and you would have to tap it to have the numbers show. You don't have to do that here.
