Unfortunately this watch does not meet expectations. The pedometer calculates not very bad. I regularly walk 1.9km and 4.5 km tells me. As bcp products of this type, some features are not easy to understand despite record (too many patterns!) And abbreviations of different modes are in English on the watch. Since I (late February), cardio mode works and flashes continuously, so to touch her again. I recommend heading to the best known brands in stores where professional vendors are there to guide you. To avoid it!
