Am super excited about the device and it can only recommend. But you have to know that you can not put yourself on the back O step number. For me it's an advantage because I do not accidentally delete something (what happened to me with other pedometers). The counter turns night at 0:00 clock automatically reset to 0. He has super mounting options is easy to read, easy to use ... and rubust (he struck me already 3 times to refrain from waist to the floor without damage) .... Great device!
