“A seriously good monitor - accurate and easy to synch to my phone and Wahoo bike computer. The strap and sensor electrodes are wide which makes for a better fit, faster detection of my heartbeat and the strap is less likely to curl and twist. This replaced a JetBlack chest band sensor (which was ok). The Wahoo is superior and well worth the extra cost. The monitor has coloured diodes which are good to let you know when it connects. Highly recommended”
