Has anyone had both(Knockaround, and Shady Rays)? Is the build quality about the same or is one a little better? I'm not expecting either to be amazing but if one is a little better than the other I'd rather go with that.

I've read somewhere you can only use the Shady Ray warranty(broken or lost they'll replace for just shipping) twice. Anyone had experience with this? If that's true you can only get 3 pairs for $62.78(first one 45 next two just shipping 8.89ea). If you asked nicely/get a nice CS rep you might be able to get more for just shipping, but wouldn't be a sure thing this would give Knockaround the edge.

Knockaround you could just keep getting a new pair for $20. So three would be $60 for you non-math wizards.

Blender eyewear I've heard has really good build quality for being cheap but they're like $45 with no warranty like Shady Rays. Is it substantially better?

All prices are for polarized shades.

Anyone have any insight, thanks.

(I've had designer sunglasses but when they scratch bad and you replace them(even with ie.sunglass hut 50% off deals) it hurts the banks. I've had another pair misplaced/stolen. I'd rather get one's I don't need to worry about every second, so when that stuff inevitably happens it's no big deal.)
