This flosser is portable with a five-ounce water tank and takes up very little space on a countertop. This is good news if you have very little free counterspace and share your bathroom with others. It runs on just 3 AA batteries which can be purchased at any grocery or drugstore. You receive three types of flossing tips along with the waterproof device. Select from one of two water pressure settings on this flosser depending on the type of cleaning you want. This gives you the option of a heavy-duty cleaning or a lighter one. This device comes with a convenient travel bag and is a handy item to take along on a short trip or vacation.
