These are the best looking most comfortable safety shades I've ever worn - they're all I've bought for years. If I had to find a flaw with them it's that the rubber nose pads eventually fall off, but it usually takes several months of wear for this to happen. They're easy enough to glue back on with hot glue or RTV assuming you don't lose them. The only other thing is that the lenses scratch fairly easily, but this is surely the case for any comparable plastic lens with a mirror coating. Considering the price, I could go through a pair every couple of months and not complain.
