I tried different brands of mirrors that have the straps and could not get them to secure properly. I now have the grand aero 3 towing mirrors.
They do vibrate some what but are adjustable in width and work well on my Jeep Grand Cherokee.
I think it depends on what model of tow vehicle you have, the shape of the mirrors, that will determine what mirrors work for you.
No one makes the clamshell snap on mirrors for my JGC. I would have preferred that style.
