These anchors are a brilliant design. I use them on all of my Peak Design bags so I can use my camera strap with them. They lock securely into place and are easy to disconnect too. These are a great item to add to your Peak Design bags (and camera, of course).
Whenever I see a camera out there without these, I ask the person "Where are your anchor links?". I use these on all my cameras, from small to full frame.
