Final answer:
A collapsible baby stroller is a product that would emphasize being easy to use in its marketing, as it caters to parents needing convenience and functionality. Highlighting its ease of collapse and transportability would be key marketing points.
Step-by-step explanation:
A product that would want to emphasize that it is easy to use in its product marketing mix is a collapsible baby stroller. This type of product is designed with the convenience of parents in mind, particularly those who are often on-the-go and need to quickly unfold or fold the stroller when transferring it in and out of a car or navigating through public transportation. In the marketing of such a product, the physical aspects like its ease of collapsing and lightweight nature would be highlighted, addressing the real-world needs of parents who seek convenience and functionality.
Other products like ear buds, a basketball, or specialty running shoes may also focus on their user-friendly attributes, but the ease of use is especially central to the marketing of complex items like a stroller that requires assembly or manipulation. Understanding consumer needs and the physical aspects that can appeal to them—like an unbreakable bottle, nonstick surface, or items that are freezer-to-microwave safe—is vital for the successful marketing of products.
