Only had it for a week so far but they're holding up well. I like how they look and they seem slightly better made than the other sub-$10 sunglasses i've bought off amazon in the same style. They're dark and since I use them in the car most of the time, it's probably worth saying that my iPhone 8's screen brightness isn't enough to offset the tint on these lenses. I opted for these heavily tinted lenses since polarized lenses usually make it hard to see my phone screen at certain angles/rotations by nature. These do feel a bit oversized (they hit my cheeks a little more than usual) but I don't mind it at all. What I do mind is that the arms feel a bit tight at the ends around my big head (just above/behind my ears). I'm already getting used to wearing them so I don't think it'll be a big deal, just worried about extra stress on the arms and the hinges. Hopefully the nice matte black paint holds up to my sweat and general wear and tear of being in my car or pocket.Will update if I run into any problems.
