Review Detail

hi What's the problem? my friend buy produkts and can not write a review of it's original product? if the product is original as the effects? he describes as the effects if it still only starts? Write a review and what goods ordered and it's original. What more needs to be? Each evaluation must have a result? if a beginner and does not know how the product has effects like Write a review? It is unfair, it should write a review or original has been delivered, and whether the customer is satisfied with the product.
