4.8 stars from 11,000 reviews looks convincing. But a rating on a sales page is written by the seller, so it deserves the same scrutiny as any other claim on the page.

Check four things. First, does the rating link to a review site where you can read the reviews yourself. Second, are the testimonials signed with a full name, a place and a photo that is not a stock image. Third, is the review count plausible for a product that launched recently. Fourth, do the quotes describe specific results or only praise.
