Aggregate customer ratings lean positive, with most ratings in the five-star category, but a smaller share fall in the lower star categories. The figures alone do not explain why customers rated it that way. For buyers considering the stated corded setup and accessory-heavy kit, the ratings offer limited reassurance rather than evidence about particular performance or durability.
