Level configuration is very simple: you set the time, weight and the approximate size of your steps. For the latter variable, I admit it takes a little at random, we would have liked a system that automatically calculates the length of not (as was the case on my phone Sony Ericson).
Counting is effective. It displays in real time the number of steps taken, distance in km, number of minutes, the number of calories but also lost time (very convenient). It keeps the results day by day for 1 week.
Since I have this pedometer I am motivated to walk / run for hours. It is very compact and lightweight.
It can hold on to his key ring, keeping it around the neck (chain included) or in his pocket. In all cases it is incredibly discreet.
The CR2032 cell battery is easy to replace.
By pulling on its end a mini security alarm sounds, used for example in case of aggression: it is noisy but nothing to do with the decibels generated by a real alarm.
Too bad it is not possible to have a backlight for night, for example, but otherwise I recommend.
