Aggregate customer ratings lean positive, with most ratings in the top two star categories, but a smaller share are at the lowest rating. These figures do not reveal what buyers liked or disliked. For owners of the listed 500-series models, confirming the model and whether the full set of maintenance parts is needed is more decision-relevant than the rating pattern alone.
