I had a Waterpik Sonic Fusion before but after a little over a year of usage the battery failed. So I bought a Waterpik Water Flosser + Oscillating but it didn't do as good a job as the Sonic Fusion. So I bought another Sonic Fusion and I hope the battery problems have been fixed. I love the way it cleans.
I would recommend this to a friend!

Great double action. Brush teeth and clear debris between teeth. Clears under bridge as well. One has no idea how much is between teeth after brushing unless one uses the water pik.
