There is a reason Amazon.com dedicates so much space and effort to user submitted reviews of products they sell. Reviews increase engagement and sales. They add to the unique content on your site, which is good for SEO. They bestow credibility. If there are legitimate reviews showcased on a product page, then the user is obviously not going to be the first to buy your product. The path has already been trod.
So allowing product reviews on your e-commerce site is a good best practice, especially if you have products that are unique and can't be purchased anywhere else. This is very easy to implement in Drupal Commerce, as we did with All Cart Parts.
