Violence in my mouth
I have had a sonic elite electric toothbrush for years that works well, except that the last (very expensive) replacement head I bought was giving me trouble.  After reading the positive reviews on this much less expensive brush, I thought I would try it.  I barely lasted through one toothbrushing session.  The action of the brush is so aggressive, my jaw was shaking wildly. I felt like I was in a torture machine.  I am used to using an electric toothbrush so it wasn't the adjustment from manual to electric.  This is just a wild machine.  I won't use it and haven't a clue what to do with it now.  After using the Oral-B once, I can see that the investment in the sonic is worth the money.  In a word: ugh.
