Yes, they seem to be a really good option, they can be left in and the windows still open and they almost look like a deep tint, which can look good too!
I can second (third) these sun blinds. They are great for my boys in the back of the car as the blinds still keep the UV, glare etcetera out even when the windows are open.
From the outside they will also give your car the tinted window look which I believe only makes the car look better.
Some would think they're expensive but certainly not compared to a decent window tint fitting, as an added bonus if you ever decided to replace your A2 you could simply remove them and put them in the 'new' A2, something which isn't really an option with having window tint film.
Ive had these fitted to 2 A2s and 3 A6s now. They have been the first thing I've purchased each time I've changed the A6 to a newer shape.
Yep another pleased customer for the blinds option here too. I'd considered tints first and had quite in hand them learned of the custom blinds option. Worked out well ?
