Hello, This is from a presentation on childcare products. It mentions the "rentabilidad del producto" often. I know rentabilidad in a financial sense, but I think what we are talking about here is how much use you get out of it. And I'm not sure how to say that in English... It's usefulness? It's advantageousness? It's something to do with it's usefulness and it's price. Value for money? Usefulness for money? I can't think... practicality? utility? One of the sentences is: La multifunción es la máxima expresión de la rentabilidad. Multifunctionality is the pinnacle of practicality? Multifunctionality is the ultimate expression of utility? ¿Any ideas, foreros?
