Motorcycle meant I went with quadlock case.

But am now in the quadlock system of attaching my phone to anything else.... IE car mounts too. SO quadlock got a bunch of my money.

Maybe I'm a buyer trying to justify my sunk costs, but to Quadlock's credit, once all matched, I think it works well.

And for the 3D printerists, there is a bunch of Quadlock 3D models to help out too.
