I was pleasantly surprised that I liked these - initially. The case is quite heavy, but considering the price, I appreciate the sturdiness. As I tried them on for the 2nd time to commit to them, I noticed they seemed "off". Yep...I pulled out my measuring tape and the lenses are not the same size/shape... like 1/2 inch off on one. One seemed more round than the true aviator shape, which I didn't notice the first time I slipped them on. Sadly, for the price, they go back.
