Killer Confusion (sum/product/look-and-say)

(Published on 25. November 2023, 15:45 by Al Fresco)

Normal sudoku rules apply.
Each cage and diagonal clue is exactly one of the following types:

Sum Digits cannot repeat and sum to the given number.
Product Digits multiply together to equal the given number.
Look-and-Say The first digit of the clue indicates exactly how many times the second digit appears in the cage or on the diagonal.

Example. For a three cell 12 cage,
(7,1,4) is a valid sum,
(2,3,2) is a valid product,
(5,2,5) is a valid Look-and-Say fill,
However (2,3,7) and (6,1,2) are both invalid fills since they simultaneously satisfy two clue types.

What a masterpiece!

I nearly gave up after so many times i glossed over the right option, but it was just too good of a puzzle to give up on, and it was well worth it :-)

For me it was a 5*
