Review on Garmin HRM-Dual heart rate transmitter, black, unverified by Danuta Andrzejewska ᠌

This expensive heart rate sensor is no better than the Chinese one for 1500. The strap is slightly better, but very often unfastens and fails at the most crucial moments in the competition. The sensor itself worked for the first year without any problems, but now it sometimes freezes at a certain pulse and can show it for half an hour in a row. Sometimes it's just that communication with him is not established and that's it. In general, he removed it away. Now I use Chinese and I don’t know grief.
