The Linear Q is meticulously controlled throughout every aspect of its manufacture. From its precision-ground stainless-steel shaft to its bearing sleeve assembly to its machined handle, tolerances are controlled to just a few thousandths of an inch. The result: a top-quality cue unlike any other on the market. Its simple and elegant appearance can be deceiving, obscuring years of research and development that is integrated into every facet of its design. A one-year product warranty covers parts, labor, and shipping costs if any defect is found.
