Dual killer

Normal Sudoku rules apply. The value of each cage is the sum of all digits in the cage. Cages that are orthogonally adjacent (i.e. share at least one edge) have values that are in a 1:2 ratio. Digits are not allowed to repeat within a cage.

Very nice puzzle, easier than it looks, 2 stars difficulty is about right.

Very nice puzzle! The logic came naturally but required you to think about multiple areas of the board to break in. I think 2* is an accurate portrayal.

Definitely not an "Easy" solve. Following the trail of killers / doublers to deduce the values was quite fun! I made a bad assumption once. Fixed it. Then it was quite satisfying all the way. Thanks! Positively a 3-star puzzle. And 100% enjoyable!
