Gopro mount emergency repair

I started with RAM mounts.
Now I use the Gopro mounts. These are fragile and tend to break.
They are also not equal in size.
The rubber tongue that secured the buckle tore.
That gave extra shaking.
So I cut an eraser to insert it to jam the male buckle in the female one. When I had no eraser I cut a small twig.
But the eraser fragmented and I had to use a rubber band.

this isn’t a gopro mount I recognise.
I’ve used one of their mounts on the bike, mounting the virb usually, and never had any reservations about its durability
