Stingy Cages: Is the solution to this Sudoku Generousity?

Today's Video:

Hmmm, I just realised Sujoyku meant stingy, as in thrifty (hence the killer cages don't share too many digits), not STING, as in that jellyfish stung me.

I'll go have a lie down now.

Rules:

Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.

Digits in a cage must sum to the clue in the top left.

STINGY CONDITION: Any two killer cages can have at most one digit in common. For example, if a cage contains the digits 1 and 2, no other cage may have both of these digits.
