Very disappointing! [SEP] Purchased the Oral B Professional Care 3000 after reading reviews and their advertising that dentists recommend it. I had been using a Sonicaire Elite for over 5 years with great results, but that unit died and it was time for something new. Short story is I have returned the Oral B to the manufacturer under their great 60 Day Challenge policy. In my experience, the Sonicaire is a much more effective product for the money. Just received my new one from Amazon yesterday.<br /><br />Pros:<br />-Bit less expensive than some Sonicaire models.<br />-60 Day Challenge which enabled me to try and return it.<br /><br />Cons:<br />-My wife and were both unpleasantly surprised at how much the units vibrated our heads while brushing. Certainly not inspiring us to brush more/longer.<br />-Used the unit for about a month and had a dental cleaning. Hygienist said I had more stain on my teeth and gums were more raw than my previous checkup just 4 months before. Only change in habit was the Oral B toothbrush.
