A great price to be sure, but you can tell that they don't match the quality of original Oakley lenses. We'll use them and abuse them and then replace with the originals when the time comes. No fault of the product or manufacturer of these lenses, they are what they are- a less expensive alternative. They will fit the bill for the time being. They do fit into the frames well, with a nice tight fit. It'll just be our preference to go back to the original.
