They looked a little sloppy at first, but they have worked well. I wouldn't take the black ones now, I'd take the brown ones
The insert frames did not fit directly into the clip, but by slightly modifying the plastic, the frames snaped into place
Fits well and now I can wear my prescriptions with eye pro instead of choosing one or the other
excellent product and seller
The field of view is surprisingly small, so I ended up returning the product.
