Walk the line

Small, light, discreet, this pedometer will accompany you during your walks or workplace without disturbing you. The adjustment instructions can be found on the net, clearer than that provided, but it is simple, the battery is included which is rare, but beware, it is a test battery that has a life span of less than trade (see instructions)
Playful, you can measure your distance traveled, your numbers of steps, your calories expenditure (he'll have to do it!) Decent price for an interesting but not essential item for our curiosity.
