Integral with any high-performance product review is how well it can presell the reader, and that is completely different from selling the reader. The biggest advantage of effective preselling is that you won't face the typical objections that are usually faced from prospects as you're not doing any direct selling. When you analyze a good review, you will find elements of copywriting, preselling and the parts that are specific to the review process. If you're an affiliate marketer, you would know the meaning of creating a strong presell and how it helps you get more sales.

In a way you need to very quickly convince the reader about the importance of knowing what you are about to explain in your review.
You will always find something in any product that is lacking or not done in the best way, and do not be afraid to talk about that.

Your last paragraph should serve the function as a conclusion, and you can talk about many things including a recap and others.

Anything you can talk about from your own experiences can be put into the conclusion too. You can also talk about all that was fulfilled by the product or anything else. If anyone has read all the way through to the end, then chances are good they are receiving what you have written in a good way. There are lots of ways to make money with affiliate products, and the product review is one that can be extremely effective. Reviews are so powerful because people naturally want to read an unbiased review before buying. If you are relatively new to everything, then take your time and get some education about how to write excellent reviews before trying it blindly.
