First pair, less than a week of wear. Nosepad falls completely off WHILE I AM WEARING THEM. Ordered a replacement pair and paid up for a pair of replacement polarized lenses. First day receiving them and the arms are completely off balance: And...that same pair two weeks later. The polarized lens just fell out while wearing them. I popped it back in and it fell out the next day, cracking on the floor. Can't imagine an Air Force pilot being too happy with that happening mid-flight.
