I put these in my barn when we built 15+ years ago and love them. Never had any issues. Absolutely love that there is nothing to stick out and get caught on like the side sliding closures.
Every once in a while, if someone (mostly DH) doesn’t make sure the door is fully slid closed the latch does not catch up top, but it has never allowed any of my horses to escape or even slide door open.
Never had any interference from the drop down grill that is the top half of the stall nor from a horse playing with them (and yes dear pony loves to grab his halter off the adjacent hanger and toss it to the floor when he is ready to go out).
I would put them in on any new stalls/barn in a heart beat.
