When reviewing a product, I consider the key features, my own experience, as well as the audience. What makes the product stand out? What makes it the best out there? These questions should all be answered, though not in a obvious way. Including my own experience with the product can also help create a feeling of familiarity with the reader, and possible help then relate to the products use. A review should entice other to buy the product, while being honest and humane.
