How liberating and especially: It really works! The pulse is found quite quickly, faster than the satellite (and that goes in a usual time). I have the heart rate with 2 of my Brustgurtuhren compared (yes I had 3 watches here), and lo and behold: The values were in all 3 watches annähend identical (sometimes showed a little more time to another). The service I find really thought through. If one has einma incorporated in the system, it is very easy to use. And above all: No more buttons that you can accidentally press a backhand motion. 3 readings can be quite fast on the display adjusted individually (1 of them big and this can be replaced quickly during the run by another value). The Armbind is good, do not bother. The closure is something different than you otherwise usual, but no better or worse than other watches. Desing and color is a matter of taste, I like it just fine, but the most beautiful of my watch, it is not. Software is only required for coupling to the PC, you can install it from the TomTom site. The evaluation of the training values take place online virtually in the cloud. This is a matter of taste but has the advantage that even after a crash still has the data available and you can always watch also externally. About this site trainings can be loaded at the clock, which is also very chick. The price is not without, but you also get what properly commanded.
