Glasses worked good while they stayed intact.  I dropped it once by accident and couldn't get the lens back on its frame, no matter what angle or finesse I took - and, trust me, I've put many lenses back on their frames (like Oakley and Ray Ban) when those glasses accidentally got dropped.  Being a bit biased here, I've given this brand of glasses three stars instead of less because I discovered that, if you turned the glasses upside down and read the logo, it very much resembles my first name "Jose". :-)
