These hold up well, still using them after more than a year now. Polarized shades work well. Seller 1st sent non-polarized shades and then was somewhat rude in her response to me regarding my feedback - like it was my fault the wrong ones were sent. But she sent me 2 or 3 polarized sets to make up for the mistake - never apologized for her "smite-ness" but I'd probably buy more.
