These fit right on the mirrors of our little honda. It is so low to the ground that we have trouble seeing what is behind us, and wanted some extra "eyes". these are perfect! Now there is no more blind spot! These are clear and easy focus too, so I have the peace of mind of kn owing that I am seeing what is behind me and I will avoid accidents! I am glad that I decided to try these out! they are durable. They are small so don't take up a lot of the rest of my mirror, but big enough I can now see all the way behind me.
