Darty changed the rules of reviews to ask for them a year after purchase, not a week
A French appliance retailer realized most reviews are written too early to be honest, so it only invites feedback once a product has proven itself over time.
Darty
the move
Darty's durable-goods model depends on trust that a product will last. Yet the reviews customers relied on were written days after purchase, before a washing machine or oven had shown whether it was any good.
Publicis Conseil and Darty recognized the flaw was timing. 'Let's Make it Last' asked shoppers to review only after they'd used the product for a year or more, so the feedback would reflect genuine long-term performance.
This was part of a broader strategy shift: Darty moved its business model from pure sales volume to creating value over time, and customers are the lever for that change, so they had to be brought along.
The result was a set of reviews that actually supported the brand's durability story — and that only a brand confident in its products could invite.
why it works
- It corrected a real data bias (early reviews) rather than manufacturing a claim.
- Aiming for late reviews only works if the product holds up, so it signaled genuine confidence.
- It made the sustainability promise measurable in an observable signal people already trust.
- It created a differentiating asset competitors with quick-drive review programs couldn't copy without admitting the point.
what transfers
Before changing what you say, change the metric. If your data is biased by timing, fix the collection window — often that single change makes the whole claim more believable than any new message.
what came after
The campaign was shortlisted for Creative Strategy at Cannes Lions 2024, promoted key brand metrics including trustworthiness, value and a sense of affiliate — and WARC profiled the strategic logic. The 'review later' idea became a reference for how sustainability claims can be made honest and evidence-based.
