So, first round with 14km running. Have the chest strap applied lightly moistened, turned on Bluetooth, launched Runtastik. He was immediately recognized and displayed the pulse. Then I started walking with the best running weather. After about 10km, it began to rain and I was twine dripping wet. From there, the pulse was no longer included. Whether it was now because I was wet through and through, or my cell phone contact with the chest belt is no longer could find I can not say that will show more runs. Will then continue to report.
2nd round. Chest was unfortunately not immediately recognized, then folded but with the connection tool located in the app immediately. Started walking and an 8 km round interval training completed. Unfortunately, I realized that was recorded more minutes no heart rate after 10. This is no longer so great.
If the now happen again, I will return the belt and bring me a normal Running Watch with chest strap.
Round 3 and 4. Can not say anything good, unfortunately more. Chest strap is indeed recognized immediately when you turn the app, but the heart rate display fails repeatedly. But the phone further indicates that it is connected to the chest strap. Whether it really is now on the chest strap or the two do not match, I can not say exactly. It's just a shame, because in itself it really is a class thing. Will return the chest belt again and again run with my old chest with clock and entering the pulse manually Runtastik. Shame
