This thing really works

My wife and I walk on a set course around our house usually 12 laps. About half way through, we would start loosing count of how many laps we had done. When she got me this watch, I was amazed at how accurate this watch is. We will walk 12 laps and the lap counter will go off within a 3 foot area every lap. Sometimes, at 4 miles, the alarm will go off at a different place than other times (maybe about 30 ft. difference), but hey, so what! I love it because I don't have to count my laps. It has way more features than I would ever use. I keep mine on the stopwatch mode and on every lap, it tells me what my time was on that lap as well as the total time. It will do this without me having to press any buttons. It shows me my pace that I am at. You can have 4 different functions displayed at the same time if you want. I would not trust the distance counter to survey land or something like like, but for exercising, you can not beat it. The battery stays charged for at least a week or more.
