Poor durability- waste of money
I purchased this on June 28th and on August 22 I am down to my last pair. The screws that hold the end pieces into the lenses work themselves out in about 3 weeks of normal wear. They aren't Phillips or Regular, it is a nut that holds them in place. Unless you have a minuscule wrench, there is no fixing these.  Tweezers didn't work.  I've been wearing this final pair for a few days and it is already loosening up. All three pairs did the same thing. That's 100% failure.
