A measure by which the value of a product or its usefulness is determined.

There are two categories by which a consumer evaluates a product. First, the most important thing is that the product must have a practical benefit for the consumer, not be a dummy. Secondly, this is the aesthetic side. Often, the consumer evaluates the product not only from a practical but also from an aesthetic point of view. You are more likely to choose a beautiful product than a product that performs the same function, but has an ugly appearance.
