I usually prefer a larger head on a regular toothbrush, but the smaller size waterpik brush is so much easier to use. My husband and I share the device & i like that a set comes, one silver at the base & the other white.
I love this product, and the warranty that demostrates its a quality item. I recommend it anyone as a great investment for properly taking care of your teeth. I can feel the difference each and every time I use my sonic toothbrush.
