Cardiosport TP5 Heart Rate Monitor, Bluetooth & ANT+ Soft Chest Strap

Functionally I did like how easy it was to buy this, hook it up to my phone using bluetooth and then have an app record my heart rate.What I didn't like is how for more than half my runs, I'm finding that the HR monitor is clearly sending invalid data to the phone during the latter third or quarter of the run, where my heart rate is reported at the equivalent of resting or standing/non-exercising values. My goal with this device had been to having a detailed record of my HR for the entire workout to do analysis afterwards but this is now impossible.

The TP5 does exactly what it says on the tin. Bluetooth and ANT+ works with all my apps and Garmin bike computer at the same time. It is also very light and small, you hardly notice it.

Looks like mine unit is damaged, stopped working after several weeks. Tried a new battery, but seems issues with electrical circuits inside it.

All good
