 Hard but doable without chains. Highlight: a combined setti. Many thanks, hepa!

Like BP, a really hard nut, took me about 3.5 hours. Additionally I used 2 URs.
Great puzzle, hepa!

 hard stuff for me
after Setti 5 and 7 and a xwing on 4 see no progress
then testing the 4's with the result that 4 must be in every row and column, still a way to the end

 Easy with hp's hint (9*4). Without the hint stuck with no next step to see.

Maybe one of the creators can give a hint not that powerful as hp's.

My final key was a hidden UR in the lower right: There can't be X-wings on 4 AND 5 in the same square.

A fine puzzle but not exactly easy. Both decisions, high/low in column 2 (it seems advisable to deal with this first) and high/low along the \-diagonal truly require some effort (and took me close to forever but without tools).
