Aggregate ratings lean positive, with most ratings in the four- or five-star categories, but a notable share fall in the middle and lower categories. Without written feedback, those figures do not identify what customers liked or disliked. They offer limited guidance on how well the stretchy, hook-attached holder works for a particular backpack or helmet.
