OnlySP: What is the purpose of a product review? A review is a summary that highlights what is good and bad about a product to help make a decision on whether or not that product should be purchased. I also pictured a review score to be a summary of that summary – giving you the basic understanding of what the reviewer thought of that product based on that score. If the score is not enough for you to help you decide whether or not the product is right for you, you can go back into the review and see more detailed information on why he or she gave the product that score. You can then use this information to determine whether or not this particular product is right for you. That’s what I thought a review was, anyway.
