How to write a product review
Research the product.
In order to demonstrate to your readers that your review is reliable, make sure to conduct as much research as possible before you begin writing. A thorough knowledge of the product, its evolution and its competition will allow you to write something approaching an expert review.
Read the manufacturer's website, as well as any manufacturer information included with the product you are reviewing. Beware of publicity material released by manufacturers and retailers-readers will often stop reading if they sense that publicity material is being used rather than observations drawn from real-life experience.
