Aggregate ratings are mixed: most fall in the five-star category, while a portion are one-star, and the small rating sample does not establish specific strengths, defects or reasons. There is no written customer feedback to explain those ratings. For buyers, the key practical point remains the listing's caveat that performance depends on the separate DeWalt battery and exact device compatibility.
