The initial challenge to 'Spot the 5 differences' between two seemingly identical phones.

The ad opens with two identical smartphones side-by-side, labeled 'Secondhand' and 'Refurbished'. The screen then transitions to show a single phone, with text appearing sequentially, highlighting the benefits of refurbished products. The pacing is moderate, with quick cuts between text and phone visuals. The final scene shows the BackMarket logo with app store download buttons.
