I've used this adapter the same way as in the video many times. It came off a couple times in rough terrain in transition through a dip in the field. I think it happened once on a box blade and once with a brush hog. On more tame terrain, I bet it'd be fine. It sure is fast to hook up that way!
The difficulty for my particular setup was that it made the top link quite a bulit longer (extends out quite a bit from the quick hitch) and I had to run the adjustable top link almost to its fullest extension.
