It is a beautiful training tool. Acquiring satellite is very fast and amazing accuracy. The touch bezel does not present any inconvenience read here and there. The connection with garmin connect is incredibly easy. Question autonomy: I lost ~ 20% per day with 1 hour of racing. If I force myself to blame: - Still a little big for a watch every day and despite all the current display is a little small, we have to concentrate to read the information. - You can store only one route at a time on the watch and thus repeat a course with the virtual partner must be planned in advance. - The chest strap does not unclipped, it must go through the feet or head.
