Review and feedback are sometimes used interchangeably by Amazon users. After all, both refer to a testimony from the buyer and both involve a star rating from 1 to 5. However, a review refers to the product, while a rating refers to the service (i.e. the seller’s performance). A buyer’s review will affect the overall appeal of a product, which is why Amazon does not allow incentivized reviews. But it can only affect you directly if you’re the only seller (left) offering that item, because a potential buyer may think you fulfilled the order that a certain comment is referring to.
