Just bought em today and I love everything about them so far. A little on the heavy side, but heavy is good; heavy is reliable. Spring hinges seem to be high quality.
As others have said, they do fit a bit small, but that was a plus for me since I don't care for the "I have a windshield on my face" look. If you have a wide head, go with the windshield, otherwise these will probably fit you quite nicely.
