I really loved the Dior pair, but I can't justify spending $600 on a pair of &#34;trendy&#34; sunglasses. I got these, and other than the cheap screws they have on the front (the Dior pair doesn't have them) they are pretty much un-clockable for being knockoffs. I ordered multiple colors (thanks amazon/the seller for free shipping and returns) and I found that the silver and the black were the most authentic looking (the black after I taped around the screws and went over them with a Sharpie). You have to be careful not to smudge them and they are very prone to getting scratched so keep them in the case.<br /><br />HOWEVER.<br /><br />The silver pair has lost two screws, but that's what you get for $18 sunglasses. If you understand and can deal with this you will just keep trading them in for a new pair. I intend on doing this, hopefully this is just a manufacturing issue with my one pair and not the line in general.<br /><br />OH, and the coating on the lens could give away that the shades are cheap. it isn't consistent and can be seen but the average person wouldn't be able to tell. it's only able to be viewed in certain light and is on every color.
