super heart rate monitor (use it with the Moto G)

The belt connects to jerk-twitch with a smartphone (in my case, the Moto G). You have to just stick to the description. I'm using as a running app Runtastic in the Pro version and here the values ​​are currently displayed and overruns can be warned by voice output.

The strap fits comfortably on your skin, does not slip and is created quickly. The actual heart rate monitor is fixed with 2 press studs and can be easily removed. The belt itself is then washed. I think that's very good.
Since I have the heart rate monitor only a few weeks, I can say nothing about the battery life. But Bluetooth 4.0 is indeed very low power consumption. Are Sportplus believe in terms of more than one year.

I can recommend the Heart Rate Monitor in any case.
