It's been three months that I use and I'm not déçu.C'est a great product, a must if you exercise régulièrement.La gps sensitivity is very bonne.L'ergonomie copy product (easy to take control) .I recommend it, the investment is worth the downside détour.Seul read on forums (one or 2 times) on the back of the watch there is a hole and force to sweat (after several visibly months) it generated moisture problems inside the montre.J'ai set for myself a small piece of tape to compensate for it in case ... and I tranquille.Cordialement priori. Frederic.
