Good for running power and some running dynamics due to software version 6.3
3 of 3 found this helpful This is an earlier generation HRM-Run heart rate monitor and has an accelerometer to give information about running dynamics (and works with compatible Garmin watches to give power information - through Connect IQ apps). However it ships with the earlier software version, 6.3 and does not seem to update (through the Garmin Forerunner 645) automatically to 6.6, which is necessary for having real time monitoring of the ground contact balance, stride length and vertical ratio. If you are looking for a cheaper alternative to the latest HRM-Run strap to provide you running power stats, this is great. If you are looking for all the bells and whistles, there are realistic limitations.
