Wifes got the good camera with her up in Alaska so it's my crappy cell phone pics, sorry.
Let see if i can clear up how it works.
The hook
The bracket
I slipped the hook into the slot in the bracket, them pushed the epoxy putty in through the hole in the back of the hook to fill the thin slot of the bracket and reduce the gap of the hook to the thickness of the bracket. So I've recreated the section in the yellow box out of the hook, and the bracket slips onto it in the same manor.
Then I used the supplied 3m adhesive strip and stuck it to the mirror.
I was scrolling through the pages today while driving, it works great, just a light push on the corner and the next page popped up. I'm very happy with this 2nd design.
A couple crappy night shot's.
Hook, see how I put in the putty (light gray)
