Aggregate ratings lean positive, with most ratings in the five-star category, but a notable one-star share means experiences are not uniformly favourable. The ratings alone do not explain why customers rated it as they did. For buyers, fit and adhesion are the practical points to assess, especially because the stated dimensions and suitable gap range are not consistent throughout the listing.
