I was able to order mine via Donagheys and they worked out way cheaper than the reimo ones. I think they work much better too as the front window blind slides up from the bottom which means you can put them part way up and get a bit of privacy without loosing all your view/light. They also work with the rain sensor unit on the window if you have one, I don't think the reimo ones do. They really darken the inside when closed even when sunny out. So far we have had no rattles at all from them while driving which I hear is a complaint with the reimo ones. Really simple to fit too as you can see in the video.
The clip is in German so skip to 50seconds in to see them in operation.
