Since Amazon both directly sells ozone machines and allows third party dealers to offer products for sale on the site, there are a variety of ozone generators with reviews in the search results. These reviews have to include a star rating out of five, and often include a list of both pros and cons for the product. Users can ask questions about the product and comment on reviews for more detailed information when necessary. Each review can also be rated on usefulness.
Overstock also requires a rating out of five stars, so users get an immediate visual representation of the review. All reviews are averaged out for a single star rating. There are a few required questions reviewers must answer, so readers are guaranteed some consistent information in each review.
A2Z Ozone Inc. continues the five star rating system, and the reviews are simple and straightforward. Each review has a heading and a body paragraph, and they are organized with only a few per page, so reading through reviews is easy to do.Learn more about Appliances
