The small device is very easy to use and the settings can be changed very easily. The pedometer shows almost exactly the distance covered in km or steps on (checked with GPS device). The bracket for the belt is somewhat unreliable. For me the device, without I realized it hooked, somehow while walking, etc. maybe by contact with an edge, and fell at the end of the walk out of my shirt. Better security would be desirable. Perhaps by a small ring. The device works reliably but without problems even in your pocket or jacket pocket. One should take out of his pocket only when man has nervous feet and like bobs with his foot while seated. Since one has quickly a few thousand steps more than you really did. :-)
