I know - it was quite annoying when people were waxing lyrical about a "game changing" innovation 😂 I have actually bought a pack or 2 of Hunt couplings and, tbh, they arent very good - they break too easily, which for a commercial product sucks. At least when mine break, I only have my own shoddy handiwork to blame and am able to repair them - you cant do that to a Hunt coupling! I have to concede defeat though, when they have produced ones that dont have to be correctly arranged, pole to pole. I have also used the ones that fit the older Hornby mk3's.
