Excellent alternative to more expensive GPS's and old-fashioned 'clickety-clack' pedometers. I can vouch for the 95% accuracy. I don't like the auto-resetting function of the pedometer but maybe I just haven't figured out how to use it properly. I do like how it records data by date. Prior to use, you do need some patience and a 9-yr old child to help teach and motivate you to figure out most functions. I would ask Tech4O to come up with a model that has a better crystal. Mine is pretty scratched up and I might pay $50 more for one that's more scratch-resistant.
