Has anyone used a keyhole holder?

Wondering about this...looks pretty simple.

Also, anyway to make this easy clip on and off so I can get my pack off easy?

Thanks, Dee

I used a PeakDesign Capture Pro on my left should strap in my chest area to secure a Canon 6D with a f/4 16-32mm IS lens. I carried it for 17 days this year on the JMT and last year on a 4 night trip. Works well and keeps the camera from moving around while hiking. The Capture Pro has an ARCA plate and I have a compatible very light tripod head that mates with it. It made taken shots while wearing the backpack very easy.
