This is a great pedometer but you *must* get the safety leash or at some time it's guaranteed to pop off your belt! Once I played with the adjustment button, it counts my steps precisely--no deviation whatsoever! Another reviewer said only the cobalt blue pedometer resets itself automatically at midnight. This is a critical feature--fortunately I happened to get the right one. It is grossly misleading for the company to sell a model HJ-105 that does not reset just because the color is different!
