User Review: I bought this pedometer for my 3 year old. Why? Because I didn't want him to loose my Fitbit but he wanted a "penomener" of his own.  I needed one with digital output and buttons he could push.  I have worn it myself when he gets tired on walks and have noted several things.  It has to be mounted horizontally, you can hear the counting mechanism quietly as it works, and the spring is a little on the weak side that holds it in place.  When clipped on properly it seems very accurate, similar to my Fitbit One. The digital readout is large and the left button toggles between miles and steps.  It was just what I needed. My only complaint was the incredibly slow shipping time, taking almost two weeks to ship about 150 miles.  It did arrive, however, on the last day of the predicted estimate, so I guess I can't complain. Will buy again when my kids loses/breaks this one.
