This works good. Well, I mean it works well. Water well, not oil well. More seriously, the lap feature has no memory, so it's useless if you're timing yourself on a multi-lap run. It's only good if you are standing watching someone else run, and have pencil and paper to write with. If you want to time yourself, you need a stopwatch that has both "memory" and "lap" in its description.
