Yeah his reviews are excellent. I don't have the patience for that unless I really use all the features. So far the ROX has been great but I haven't uploaded a track to follow and likely won't... at least for some time. Basic logging and display of data for me is done with the main screen. I don't ride enough in adverse conditions to be a good review source there either.
Compared with a phone and Strava logging via the app, the numbers are at least ballpark comparable so far. Either I'm in better shape or the HRM reads a bit lower than my BT strap, not sure there but it isn't different by much.
The display in details can be hard to read. Various alerts pop up and I couldn't tell you what they say. All the main data is readable enough though.
Now that I have a few rides in, I need to read the manual again just to fill in any missing pieces.
