I bought a pair of the Streamline model in December 2010.  I drive back and forth between DC and Colorado twice a year and use them in frequently changing light conditions rather than switching back and forth between sun and regular glasses.  The lenses are excellent.  They help with glare and are able to block enough sun without darkening things too much, a problem I often have with other sunglasses.  However, the design has changed between my earlier and the current model with the later one being considerably bulkier all along the side.  I imagine the change was made to keep more light from entering, but for someone with a very small face it made the difference between looking OK and looking ridiculously heavy.  I sent them back.
