Whoever designed this Pursonic toothbrush thought it would be quite clever to NOT give you the ability to simply turn it on and off. Wildly irritating! My blood pressure is rising just from typing this. You need to repeatedly tap the on/off button in some bizarre protocol (forgive my laziness, but I'm not reading a novel-length owner's manual to figure it out!) to actually turn it off. That's because there's some "massage" option as you cycle through the buttons, and worse, the toothbrush attempts to "teach" you how much time a proper brushing should require, so it fights you if you try shut it off before the allotted 45-60 seconds. I've been brushing for 3 decades so I don't need your guidance! The motorized element seems to knock into my teeth far more often than my Braun electric, so I hope I don't lose a tooth as time goes on. Yes, it has a few pluses: the device brushes your teeth quite well, and serves its purpose. It comes with a generous slew of extra heads, which should take me forever to use. The LED light that sanitizes the heads looks cool. Nonetheless, it seems noisier than my Braun electric.... and I like the Braun's round head more than this elliptical one. I can’t recommend it.
