Отзыв о American Educational 7 1397 Цифровой секундомер от Billy Stull

Using this product, our team found that it was very easy to operate and gave accurate readings. The buttons were responsive and the screen was easy to read. One downside was that it lacked a backlight, making it tough to use in low-light conditions.However this is a well-made stopwatch that does its job superbly and is an excellent tool for science classrooms..
