Aggregate customer ratings are mostly in the four- and five-star categories, but a portion are three-star or one-star, so the overall picture is not uniformly positive. These ratings alone do not explain the reasons for satisfaction or concern. Buyers should match the tool to the listed 4–13 mm range and 60° flank angle rather than treating ratings as evidence of suitability for a particular thread.
