Received as a gift; set it up in my bathroom but realized I don't have the surface space to use it. Not used in mouth. From WaterPik's website: "The ION water flosser provides maximum performance with cordless convenience. The rechargeable cordless design eliminates clutter, and with a 30% smaller size than traditional plug-in models, ION is exceptionally compact. ION's rechargeable lithium-ion battery lasts up to 4 weeks per charge. It features on/off water control on the handle, a magnetic handle cradle, and global voltage compatibility. This professional model comes with 7 flossing tips for a variety of dental needs, a tip storage case, a convenient one-minute timer with 30-second pacer to ensure thorough water flossing of all areas, and a removable water reservoir with 90+ seconds of flossing time. The special 360-degree rotating tip handle easily reaches your whole mouth, even back teeth. Removes up to 99.9% of plaque bacteria that causes gingivitis, cavities, and bad breath from treated areas and is clinically proven up to 2X as effective as string floss for removing bacterial plaque and improving gum health."
