These seem to be decent quality sunglasses for the price.  However, I have a large head, and they're a little more snug than I would prefer, but not really too bad.  More specifically, they don't press on my temples any, but just at the far [back] ends of the ear pieces.  On the upside, I don't have to worry about them falling off.  I could see the frame size possibly feeling kind of oversized for someone with a smaller head.  Up front, the nose piece is pretty comfortable, and the lens wraps around far enough to block out bright light and glare in peripheral vision.  I don't know how scratch-resistant any of the lenses are, as I haven't had them all that long and only use them as driving glasses.  (And thus far, I only use the smoke-colored polarized lens.)  However, I can say that they work well as driving glasses - the make driving on sunny days comfortable instead of squint- and headache-inducing.<br /><br />I can't really say much about the accessories, as I haven't used them.  The case is fairly large for a glasses case, so I don't bother trying to use it anywhere other than at home.  (In all fairness, a lot of that size is just because the glasses themselves don't fold up very compactly.)
