Loving my Saris H3. I’m finding however that it’s quite slow to respond to changes in cadence and effort; by that I mean my watts output in Zwift are slow to update. The controller seems to update quite fast to changes in grade (impressively fast). It just feels like the watts/cadence sensors are slow to relay changes from my end to Zwift for whatever reason.
Also, doesn’t like when I spin really fast under light load. Maybe it’s just a limitation of the hardware? Definitely not a big deal once one’s aware of it. It makes it hard to do low watts in ERG mode however.
So far I’ve jumped between Blue Tooth and a cheap ANT+ sensor I got off ebay. They both seem about the same. The ANT+ sensor requires me to have an extension cable placed right next to where I think the sensor inside my H3 is (won’t even work from a few feet away). I’m thinking about buying a better ANT+ sensor.
My H3 has the latest firmware update (unless there’s been one released this week) and is calibrated correctly afak.
