I had its predecessor (OX1060-353 - which are identical to this), prior to Costco melting my frame out of shape when I sent them in for my with my new prescription.  Although this pair looks identical to the other pair, the quality of it is not like the other.  the frame does not feel as solid as the other frame.  As far as comfort goes, they are still just as comfortable and I love using them as my computer glasses.  After many hours of wear, they do cause a bit of a pressure on the bridge of the nose that could be mistaken as a light headache.  In general, I've had very good luck with all the Oakley frames I've owned.
