I use this watch since June 21 at 3 times a week (more than 1 month) for 1 hour each outputs, cardio zones mode. It works really well, even in hot weather (30 °) and sweating a lot (you must tighten properly). The absence of a chest strap is very comfortable compared to models I've used both and the data displayed on the watch on the PC are easy to read and comprehensive. The partnership with Google Earth is nice (pity it is always necessary that the watch is connected to read data on PC). I practice foot race since 1981 and have used other models (Géonaute, garmin ...). Tom Tom Runner Cardio is for me the best.
