We had the day/nite shades and replaced them with MCD. When two of those broke and there were no replacement parts and they were willing to give a "customer loyalty" discount of 20% on a complete shade assembly, I said no thanks. They would not sell just the shade that broke, I would have to have bought a complete set.
Took those out and installed AutoMotion Shades Automotionshade - Home
They are of a much better construction than the MCD and the fabric is much heaver. Overall, it is a better shade.
