Interesting, thanks for sharing, it looks like it has similar core sensors to the Polar H10, but I'm not sure how it compares overall

Well, the MD I linked to in [2] above, claims that it's more precise for HRV IIRC. Something about sample rates and filters and skewing of the waveform impacting HRV measurements since they depend on precisely locating waveform peaks. (he has a bunch of posts about the Movessense sensor, so I might not have linked the best one)
