Waterpik Cordless Express vs MySmile LP211 Portable Water Flosser

Buy the MySmile LP211 if you want more control and fewer battery chores: it recharges over USB-style charging, runs 30-35 days per charge, and gives you 5 pressure settings and 8 tips. Buy the Waterpik Cordless Express if you want the dental-professional brand and the simplest, lightest travel tool, and you don't mind swapping AA batteries. The Waterpik has the stronger clinical reputation and ADA acceptance; the MySmile wins on features and value for braces and pocket care.

• Choose the Waterpik Cordless Express if you want the brand most dentists recommend, ADA-accepted cleaning, and a light shower-safe flosser that runs on easy-to-find AA batteries.
• Choose the MySmile LP211 if you want rechargeable power, 5 pressure settings, and a full tip kit for braces, crowns and periodontal pockets.
