Native doesn't stand behind their product
I have a pair of Native glasses (the Dash XP) that I thought were going to be great, but when the comfy nose-piece that holds them on your face fell off Native left me hangin'. I tried repeatedly to get customer support from Native, but they failed miserably.
Learn from my mistake -- buy Smith,... I strayed from them for a short time, but trust me when I say that they stand behind their products (not a paid advertisement--I promise).
