Cheap in all respects
I mean, how much can I complain about stainless earrings that don't even last three months? The hoop was fine, but the clasp wouldn't stay closed and then snapped off within three months. Worth the price? Kinda on the fence about that.

For your big head instead.
I bought these in anticipation of my upcoming lasik procedure. These things look great and the seller even included a cleaning kit in box. As someone who is 6'3" with a larger head, these sunglasses are snug without being uncomfortable. I actually love that since my current prescription sunglasses are so loose on my head that they can fall off during light activity or when I sweat. Now that I have my pick of the litter with sunglasses, I could not be happier with the money I spent on these and the quality that comes with them.

Love them. Fit perfectly. Most important, it really blocks the strong sun rays.
