Review on Ironman Tenacity Sunglasses: Sleek and Stylish Matte Rubberized Shades for Optimal Performance by Tony Hanson

I've used them before but they're ridiculous. The first day I used it, a screw fell out and now I can't put it back in. It looks like something has to pull on the metal thing on the earcup for the screw to go in. I was expecting to get more than 4 hours of it. Especially since I had 2 pairs before. These are clear lenses and I love their design, but I just can't get over the fact that they fall apart on day one.
