I find that the smoke lenses work very well when shooting on the outdoor range. I use the clear lenses with my pistols in the indoor range. I have not used he copper colored lens yet. I must say I am quite satisifed that I was able to fill two nitches with one purchase.
Also, the ear pieces are flexible (that you can form to a comfortable shape around your ear) which make them very comfortable for use with hearing protection ear muffs.
Pros: Excellent eye protection, nearly full wraparound protection with very little to no optical distortion
Cons: Somewhat difficult to change lenses
