I used these sunglasses just for casual use around the city. I noticed when they arrived they had a bit of rusting on the joint between the main chassis and the left arm. Two weeks later the left arm completely fell off. I'm sure it would have been a quick fix but I lost the small screw holding the two together. In the end I have now just thrown them in the trash.
Feels true to size
Bottom Line No, I would not recommend this to a friend
