It's a good design, looks more ergonomic, but "self adjusting" feels like exaggerated marketing. The roller is always going to be perpendicular to the lever arm, because that's the direction your force is going. Comfier, yeah, but it self adjusts in one direction every time lol
Yeah instead using the word “self” adjusting probably would be better to just have it called the Adjustable Roller Pad or the Return Roller (since it always comes back to the same spot at the end of each lift). It would make more sense.
