Hi, Im looking for rear sun blinds to keep the sun off the kids during our holiday. I dont like the ones which stick on, especially the ones with pictures. Last year we had ones which had a car on, and every time I looked over my shoulder to change lanes on the motorway, I thought there was a car on my rear quater. Anyway, I've seen official Audi blinds for the car. https://www.ebay.co.uk/itm/GENUINE-...011721&hash=item41b2799b87:g:Mb8AAOSw~y9ZEd1s Has anyone had experience with these? Are they good? Can the window be opened with these attached?
