Aggregate ratings are mostly five-star, but a smaller portion are two-star, so the overall picture is not uniformly positive. With a limited number of ratings and no written feedback supplied, these figures do not establish why customers rated it as they did or how well particular functions work. Buyers should judge the tool against their exact vehicle and diagnostic needs.
