Have to admit, when I saw the two screenshots, I thought the OP's problem would be exactly that, not the agency process. Original design not great but has a big picture of a hardware device, an unmissable order button and some explainer videos. New design much more visually appealing, but looks like a different company, potentially even a different class of product and whilst the order button isn't exactly difficult to find, it's not shouting as loudly to act.
The bottom of the post mentioned that sales have increased by 40% with the new design. It will probably take some time to know if that sticks, but it seems like it works from that point of view, even if it was maybe overpriced.
The 40% increase is ~$18k a month based on the numbers in the article. That means that redesign pays for itself in three months. That's the type of "regret" that I want.
