Better than Flossing!

This is my first water pik so having issues doing it correctly. Unit is great, attractive, easy to fill and clean. My mouth feels so clean and my gums feel great. Love the different pressure strength and cordless feature. Very easy to use. Bonus was extra tips and cordless. Still haven't had to recharge.
