This version of the Powercal is not as good as the original PowerCal Ant+ version which could be calibrated to match your heart rate characteristics. Now I am well into my Vets years my heart rate is a lot lower for the same power than 20 odd years ago. When I compare the PowerCal to my Stages PM it follows the power fluctuations quite well but reports the power at around 50W less than the Stages PM. As long as you accept that absolute power values may not be correct for you it can still be a very useful training aid and is easily used on multiple bikes.
I use a heart rate monitor and crank-based power meters all the time. So why this? Well I wanted something that I could use when away on holiday using an exercise bike in a gym and that would allow me to use Zwift to reduce the tedium. This does the job nicely. The power readings are somewhat random, rather like those made up by Strava, But they're okay enough and mean that I don't have to stare at a blank wall or a Boring Garmin monitor. Glad that I found this really (the alternative would be to take a pedal based power meter and swap the pedals over - not really what I wanted to be doing).
