A little disappointed .... 89

Pros: comes with the belt (this is not very explicit), but I hoped, otherwise I would have returned.
The watch is good-looking, not too plastic, I was surprised by its weight.
The wristband is tough, the large-scale closure. The fund is fixed by 4 small screws, so the battery change should not be too difficult, without having to remove part of the bracelet, unlike my previous Decathlon (galley).
The commissioning is fast, you put the belt, pressing the button (the only one of the watch), and heart rate is displayed.

Negative: I thought I could switch between frequency and time display ... and no, impossible.
Either we stay on time, if you do not press, otherwise cardio display, one can only trigger the timer function.
Otherwise remove the belt and the watch returns to the time display (not very practical).
Too bad, but it seems that many cardio are like that. Fortunately for me by mountain bike, can I have the time on the counter.
