I love my natives too. The really cool thing about them is they have a lifetime warranty that covers pretty much anything except theft. If you have a cool story about how they got damaged, so much the better. Their warranty explicitly covers scratches - it also covers sitting on, stepping on, tripping and falling on your face (did that!), etc.

My only complaint with mine is that they don't vent enough, so they fog. But I have that problem with all glasses - not just these....
