## Before you buy

- The up-to-six-hour decongestion statement is a manufacturer claim, qualified by its report that 57% of subjects agreed their nose was decongested at six hours. Follow the product directions. The listing's format is given as “Drop” although it describes a micro-diffused spray, and its ingredient entry says “Maganese” while the title and feature text identify copper. Confirm the packaging details if these distinctions matter.
