Important is the correct Einrichtig, especially the value of step length must be taken into account. Omron recommends to (as spartan as the equipment of the device) to make 10 steps behind the other and divide the distance traveled by 10 in the user manual provided. The calculated value here is important for the distance traveled, the number of steps he has no influence.
All in all, the device will work here quite easily and reliably, only climbing stairs, especially at very low stairs, it has occasional problems. Who therefore not too much emphasis to be 100% accuracy and the values draws on only as a rough guide, which can zugriefen here without hesitation. From me, there are four stars!
