I bought the blue sensor mirror, my phenoms came with the red solex mirror. Fairly easy change out process, maybe 5 min of annoyance.
I bought these just recently for some travel up to Snowbird. I was blown away and should have bought these years ago to swap out with the mirrored lenses my Phenom's came with. The lenses are listed as best for overcast days but work fairly well on bluebird days and excel in overcast/snowing days along with sunny days skiing in and out of trees/shadows.
