  • Our take on the Waterpik Cordless Express Water Flosser

    The Waterpik Cordless Express is a battery-powered water flosser that runs on AA batteries instead of a rechargeable battery, so there is no charging dock or cable to pack. It is small and waterproof, with two pressure settings and two tips, and Waterpik claims it removes up to 99.9% of plaque bacteria from treated areas and is up to twice as effective as string floss. It suits travelers, small bathrooms and shower users who want cordless flossing without charging. Against rechargeable rivals like the Waterpik Cordless Advanced it gives up adjustable pressure and a larger reservoir, but it is simpler and needs no charging routine. Owners like the portability; the main complaints are the small reservoir needing refills and AA batteries running down.
