They're ok. I got these standard on a pair of Half Jacket's online. I had to change them though. I'm a fan of the mirrored finish, and the lack of the iridium coating made them unfavorable. They were nice for the time being though.
My lens is the (new) one with only 25% light transmission, which makes it more comparable with the G30 and VR 28 lenses. It really works fine in mixed conditions.
I just got this colour in on a Radar Path lens. Seems to fill a gap between brighter lenses (clear, persimmon and pink) and darker sun lenses. I use it on roadbike training in mixed light conditions. The polarization makes it easy to see the road and it is a good alternative to G30 (pink) and VR 28 (light brown).
