Personally I prefer cheap ones, jus tbecause I lose sunglasses, I sit on them, I drop em everytime.. But I guess if I had an expensive ones I would take good care of em. I recently bought swunglasses for like 5bucks and my frined copied the style but bought them for 200 bucks and in comparison, his are soooooooo much better to feel, to touch, to wear omgosh
