Familiarity: I've used it several times
I bought these as instead of the higher priced alternatives to actually use instead of worry about them constantly. I wanted basically a quiver killer for biking (mtn/cx/road) and running. So I chose the black lense, hoping they wouldn't be too dark - they're about right. In dappled light its still difficult to see with them, but that's tough lighting.
The fit is pretty good with the adjustable temples and nose, you can dial in your preferred fit/distance away from eyes. They fit pretty well with my POC Trabec helmet and I have not had fogging issues.
