And a note to self and maybe others... watch how your fingers are placed when you release those quick releases! The first one I encountered bruised me! I must have had my finger in some weird position over the top. I pushed down on the ring and the center sprung up and cracked me right in the top of the first bone as it joins the knuckle. I had that reminder for close to a week. That said... a few years later the lesson has still stuck....
