Aggregate ratings are generally favourable, with most ratings in the five-star category, but a smaller one-star share means experiences are not uniformly positive. Ratings alone do not explain the reasons. They cannot establish fit or durability for a particular differential, so compatibility and the need for additional components remain the practical checks.
