Finally, you're ready to actually set pen to paper, or fingers to keyboard. If you've done your research well, this is the easiest part of the process - at least for me. I can spend weeks evaluating a product, but it rarely takes me more than an hour to write the actual text. This isn't only because I love to write. Reviews have a very clear structure, with few variations.
First, you write an introductory paragraph. The lead paragraph (what journalists call a "lede") states the problem to be solved, and introduces the product as a possible solution. The introductory paragraph (sometimes spilling to a second one) also provides a one sentence summary: Did you like it? Is it disappointing? Provide no details, here, just the summary. Writing an effective lede is literally the subject of many books on creative writing. For our purposes, let's just. note that a lede needs to capture the reader's interest and give him a clue about the article's contents.
In the main body of the review, you describe what the product does, and how it works. While you can show your appreciation or disapproval of the features and process here, the underlying intent is to describe "what it promises."
Then, go into detail about what you like, and what you dislike. Though it's common for new reviewers to switch back-and-forth between the likes and dislikes (perhaps they think it sounds, more fair), readers usually expect the likes to precede the dislikes.
Finally, summarize your opinion with a strong conclusion. Tell someone with certainty: is this worth the money? Don't waffle; the reader has made it this far through your article because he wants to know if this product is worth his money. At heart: if was your money, would you buy this product? Tell the reader so, and explain why.
