One of the lenses fits great, the other one does not fit well at all.  Looking through the lenses I do not think they are polarized despite what the listing says.  Visual quality is meh.  Overall, Id say these are a huge disappointment.

Update:  After posting this review I was contacted by the company and they offered to send me another set of lenses if I would reconsider my review.  They sent me another pair of the lenses and they are about the same as the first pair.  The lenses are in fact polarized but nowhere near as colorful as the original lenses from Oakley.  The second set of lenses also does not fit very well in the frame, there is a slight but noticeable gap on the outside edge of the right lens.  I am going to upgrade from 1 star to 3 stars because of the great customer service.

Another consideration is despite the mediocre quality, there's no other way I was going to get new lenses for the Tightropes for $30 so in that regard, you might pick these up for that reason.
