Amazon and other online retailers have reviews for all the products, including mini dirt bikes, that are sold through their platform. The users have the option of either creating a video response or written review.
Amazon makes it a point to weed out any reviews put on by dishonest individuals. If the review is not up to par with the websites guidelines or looks as if it is being used for promotional means, they will remove it. This is especially useful, as the site offers a platform for consumers to show honest reviews about the products they've purchased and even going as far as to include time sensitive information, such as how long the product has been owned.
