I replaced my older model Sonicare with this one (after about 2 years of use, the battery could barely get me through a full brushing session). The Essence 5300's angled neck and smaller head make it easier to reach those tight spots near the back molars. One feature I've never liked with the Sonicare, however, is the 2-minute automatic shutoff. I typically need 3 or 4 minutes to get the job done. Overall, the Sonicare has really helped my hygiene, and my dental charts are proof of that.
