Which factor is crucial for determining if a product is worth its selling price?

Quality and performance are essential factors in determining whether a product is worth its selling price because they directly influence customer satisfaction and the overall value proposition of the product. When a product is well-made and performs effectively, it meets or exceeds consumer expectations, which justifies its price point. High quality often implies durability, reliability, and functionality, which are critical attributes customers consider before making a purchase.

In contrast, while brand reputation, design aesthetics, and market accessibility all play important roles in a product's success, they are often secondary to the fundamental need for a product to perform its intended function well. If a product lacks quality or does not perform reliably, no amount of brand prestige, attractive design, or market presence can sustain its value in the eyes of the consumer. Therefore, quality and performance serve as the foundation upon which a product's worth is assessed.
