I love this watch.  I use this watch to time my runs and count laps.  The indoor track that I use is 1/6 of a mile.  For a marathon distance, that's over 150 laps.  Most running watches can't remember/count that many laps.  This does.

The drawback is the tap functionality.  It's a fantastic concept, but is problematic.  On the "light" and "medium" tap pressure settings, it's too sensitive and wil count laps if I bend my wrist a certain way or jiggle the watch too vigorously (like shaking the sweat off my hands after wiping my brow or something).  The "hard" tap pressure setting requires such a vigorous tap on the watch that it defeats the purpose of having an easy way to count a lap.  I've turned the tap feature off and just use the button on the side of the watch, which I've found to be just as easy, even with gloves on.

Like I said, I love this watch and only am removing a star due to the tap functionality being a little flaky.
