It is an odd sentence. As written, the sentence is not grammatically correct, because it lacks a main verb. One should mentally change "how much better" to "it is easier". Then the sentence is a zero conditional, using present tense in both clauses.Originally Posted by jiang
"Made by product" is a typographical error of some sort. It makes not sense. The product doesn't make a pitch. I would change that sentence to "change the image or the package, rather than change the product itself."
"Rather than" is still a conjunction. It is connecting two verbals "to change" with "to go", but I would prefer only "than" here. If there is a comparative, such as "better" or "easier", one does not need "rather".
