HW706 Armband Heart Rate Monitor

Erratic readout

When the sensor is connected to zwift through the smartspin2k trainer, the readout is constantly bouncing between 5 bpm and 200 bpm. The span narrows through the entire workout, and you can tell that the true bpm is hidden in the average. But that's basically useless

Nice HRM, great value, but the button is too sensitive

The HW706 is a cracking little HRM that "just works". Nothing fancy, just turn it on, connect your watch/phone/other kit and away you go. Comparing accuracy to my Garmin Pro+ and Scosche 24 shows this is close enough (for me). The area where this lets itself down is the button - it's too easy for the unit to get turned off accidentally. Other than that, I like it.

Nice but with a few problems.

I really like this rate monitor, its really easy to use and its perfect because it works without batteries. But sometimes, when im doing small series, I lose the signal maybe 20 seconds. Thanks.
