I had some from DS for my K7 but they didn't fit as they were asymmetric in section and differed from the photo on their web site. They were actually the right length and curvature. I sent them back and got a full refund.
The quality was OK not as good as the originals in my opinion. You could probably do just as good a job using standard chrome edge trim. When I get chance I will start looking for something suitable although it doesn't look too bad without them.
