I just upgraded my Sonicare E-series to this one. I love it! I liked the old one, but I got fed up with the screw-on replacement brushes. These replacement brushes push on, so the vibration doesn't change over time nor does a lot of gunk collect around them. They aren't lying when they say it cleans better than the E-series either. My teeth actually DO feel much cleaner than they did before.
