My husband and I love these electric toothbrushes. Our teeth feel so clean when we use them, and I especially like the way my teeth and gums feel when I'm done. The timer that's included is helpful in making sure that you brush each quadrant of your mouth for the appropriate amount of time. We have had ours for a few years now, and they are still going strong. Replacement brush heads can be spendy, but I think it's worth it.
