Look Keo - Anyone put lots of miles on them yet?

Just wondering how folks were getting on with the Keos now that they are a few months old. I tried them initially but wasn’t totally smitten with the full 9 deg float. But now I hear that there will be a 4.5 degree float gray cleat for this pedal, available in a few weeks time, I am told.

How are they holding up with extended use? Any problems? Still enjoying them?
