Lens break easily

I've used it several times

Same as another reviewer - the tabs of the lenses break off easily and get stuck in the frame. I had to break out my best surgical technique to get the broken piece out to at least be able to use them with the light-gather and clear lenses. Too bad because I really liked them otherwise for air flow and not gathering sweat right in my view scope.

Haven't held up

I've put it through the wringer

I liked these at first. Did great for running and biking, without fogging up. Didn't take long before the blue lens was scratched up (I take really good care of my glasses). Comes with 3 lenses and 2 of them have broken pieces off when I went to switch the lenses. The broken piece gets stuck inside so I can't use the lens that isn't broken. I can still interchange the 2 broken ones :-/ Wouldn't buy these again.

runs too big for a medium sized face

I've put it through the wringer

Though you are supposed to be able to adjust the frames somewhat to be tighter, they just don't stay on a medium sized face, at all. After several months of using them, gonna have to find something different. I liked the interchangeable lenses feature and the price point, but they just don't work as intended.

Good looking

I've used it several times

I obtained the Gunmetal / Light Night Fototec Tifosi Optics Alliant Sunglasses because I wanted photochromatic sunglasses. These glasses are aesthetically beautiful and appealing to look at. Lite in weight. Well made. They did work in controlling the sunlight ( I live in Florida) but unfortunately they would fog up. I wear a mask while riding and although there was no issue while riding, anytime I stopped at light or intersection, the lenses would fog up, I tried placing them further away from my face and even used some anti-fogging spray but to no avail. Fogging up was the only issue I had, but I would still recommend these glasses highly based on company's reputation & quality based on price.
