I put mine on last night. The front and side silver lenses. My take....
Fronts: You cant find a better solution. If you didnt know any better, you would think they were factory. Excellent look and excellent fit. 10/10
Sides: The fit is a little "eh" but they look great. They appeared to be a bit more concave with the curvature than the fender, so tightening down on teh screw I had to be careful I didnt crack them (passenger side was a little more curved than my driver side). Once seated, they look good. My driver side lense has a slight wiggle in it and isnt seated perfectly, but its livable. I think by putting a cushioned backing on the lense, like the OEMs, it will seat better. 8/10
I took an exacto knife and some sandpaper to the backs of the side lenses to clean off some of the excess glue buildup. Flushed it down so they would seat right on to the surface of the fender. Quick and easy task in case you have some glue buildup.
Altogether, I am please with the Klearz lenses.
