Customer Review

I bought this belt to allow me to check the condition of my heart rate after running races and tennis, with a rather high base rate. For me it is very important to monitor the evolution of my pace, but without it being painful.
The belt meets this expectation being light and not too uncomfortable to wear. Several things to note:
- The strap tends to relax after a few weeks
- It is imperative to remove the belt sensor to save the batteries, otherwise it wears very quickly.
- A code to activate the Pro version of Runtastic is provided (see below)

For cons, I have some big problems of reliability, and that is very damaging blow. The sensor is properly detected 2 times 3, which is too little for my tastes. Moreover, after 30-40 'to use, it shunts to give me a heart rate of about 30-50, far from reality. It is impossible for me to monitor my heart rate correctly with this product.
Note that, although it has less than 6 months, I can not replace it, since there is no guarantee that seems to apply product.
Technical Support Runtastic application uninstall the application in an attempt to correct this, but people like me who had the application pro version with the code supplied with the belt can not afford to uninstall the application, since the code is for single use (a priori).
