When the lenses arrived I was concerned about a few dents and nicks on them. I'm definitely not impressed with the quality of Oakley these days, especially considering their high prices. we support. But back to business - the small dents around the edges weren't far enough on the lens to be seen once installed. Now that they are in place, I can move them left to right in the frame a bit, but they don't rattle and there are no gaps. I agree - the little loose part is probably part of the design so we can plug and unplug them ourselves. This is the same model/serial number as listed on the Oakley website and they are actually black iridium although they look a bit light in the product image. I've never heard of Fives "3.0" in the name of this product but I bought a recent Fives Squared last month - these lenses fit.
