I was also very excited about these... WAS... I am sending back 2 pairs of the Ferrari TinCans today. I thought I would give them a shot. The sizing is smaller than the Jupiter I had, which was way too big for me, but these TinCans are still a bit big for me. I had other concerns like incomplete finishing of the arms, the assembly of the nose bridge, the "?" material on the back of the orbitals holding the lenses in. I think its a shame as I really liked the hinges - I thought they were well done, but that was about the only part of them I like, uh... liked
past-tense.
Also, I know this is a 'fit' thread, but FYSA - I found the polarization to be less accurate than the Carbon Blades, which was a surprise. They were not as clear, many more shadows, rainbows, and dark spots in the
Ferrari TinCans I had. I expected them to be on par, and they were not.
