Overall a pretty good power meter option for Shimano cranks. Installed this on my gravel bike with GRX810 drivetrain. Seems pretty accurate and it was easy to install. My only wish is that they offered shorter crank arm options (but that's up to Shimano as well, at least for the GRX810 crankset).
Got this for my Canyon Grizl, totally unnecessary for someone of my 'abilities' but fun and should help with training etc. Using this on the rx600 grx crankset, installation was easy. Works well so far. Survived a very wet gravel race without issue.
