I never had difficulty operating QR skewers but a lot of people do. I'm sure many of us have seen people who screw the skewer tight without flipping the lever. I taught a class for adults and was very explicit: "Test to see if it's adjusted right by flipping. It should be hard but possible to close. When you have it adjusted right, do not screw it tight; flip it closed." I showed it very clearly. And half my students screwed it tight anyway. Oy vey. And I suppose this is a reason thru-axles come on new bikes.

Given that we can't change human nature, I'll concede that the change is a good one. I don't wish a falling-off front wheel on anyone.
