I use this pedometer to record how much I walk each day.  So far it is doing pretty good.  Sometimes at the end of the day when I want to see how many miles I walked it shows zero.  I don't know if it got accidentally reset or if it never started recording at the beginning of the day.  I don't have this problem figured out yet.  When it records my miles walked (which is almost all the time) it does a good job.  This is the only feature I use on the pedometer and I can't comment on any of the other features.
