I fitted a set of Heko ones to a mates Superb and thought they were good. I got another set a couple of weeks ago and fitted to my Dad's new Kia Venga. Mum likes the window down a bit as she reckons air con makes her throat sore and her eyes run.

Ebay is as good as any place to get them from. Just search "Heko Golf Mk6"
Good as they are, I still don't think I'd have them on any of my cars tho'.
