Crafting a comprehensive, considerate review of a product requires a detailed comparison between the product's intended function and the manner in which it truly operates. Thus, a strong product reviewer recognizes that a product's quality automatically dwindles if there exists a disconnect between promised versus real outcomes that it is able to produce. Another factor that is crucial to be cognizant about when reviewing a product is understanding the differing needs and expectations of each individual customer. A strong product reviewer recognizes the reality that their unique and nuanced opinions regarding an item, old or new, is not a comprehensive representation of the entire market of target consumers, regardless of how narrow.
