Hi Alan I had the eccles mounts 3d printed and they are good, but these are sooo much better. The quality is brilliant and they don't wobble as much because they are very strong. I guarantee that you will be very happy with the quality of these. They come with all the fixings you need and its nice to have all of the hinges matching. Having Spa convex mirrors instead of the standard mirrors is one of the best things I've changed on my car, as you can see a lot more. The more you can see the safer you are right? Any questions anyone has I'm happy to answer. There should also be a picture of mine below. Thanks J
