Review on Marathon ADANAC Digital Glow Stopwatch Timer for Teachers Fitness Sport Coaches - Large Display, Blue Backlight, Water, Dust, and Shock Resistant (Black) by Cameron Reed

The stopwatch works well. However, the instructions that came with it were totally inadequate. Nothing about how to set the clock or alarm. I even went to the manufacturer's website and asked for full instructions but never got a response from them. Through trial and error, I finally figured out how to turn off the alarm, turn off the hourly time signal, and set the correct time. Now it works really well and helps me keep track of my walk time.
