Exceptional quality for the price
Color: Black
I've worn these sunglasses for over 2 years now and they haven't broken; a lense hasn't popped out. They are of exceptional quality for the price and they aren't heavy. Some of these sunglasses with the side panels will sit below your eyes and when you take them off, your skin is pulled and marked up. Not these.

Get them!
Color: Black
This Sun glasses are beyond my expectations, they are comfortable, light, stylish, extremely well made, I have other “better” brands and trust me, they suck compared to this one, just like other reviews say, they are very nice.

Good but check screws for looseness, mine had an arm fall off.
Color: Black
A screw fell out and the arm fell off soon after beginning to use them. Aside from that they are fine. Repaired by buying a $10 eyeglass repair kit.
