SO HYPED ABOUT THIS PRODUCT. CAN'T WAIT UNTIL IT'S RELEASED (5 stars)

(brand) hits it out of the park again! Thanks for the review model, paid trip to Hawaii, and sweet t-shirt, (brand). This makes all (other brands) obsolete! Hail Sony! (5 stars)

This new model makes the old one look like trash. A new era has arrived (5 stars)

(review of another product) (5 stars)

Good and knowledgeable review that has an honest view of the strengths and weaknesses of the product. Might have a mix of broken English, bad production values, or be by a kid with a squeaky voice or someone who looks ugly: 3 stars

Out of stock! (1 star)

It seems like there is a viable business model underlying this, that shoulf translate to other product categories. The hard part is building an audience that trusts you.
