I love Oral-B Professional
I bought mine first.  I was so impressed with it that I bought my daughter one for Christmas.  Then I bought my friend one for her birthday.  It seems most people think it extravagant to purchase an expensive toothbrush, but it is so worth it.  Both my daughter and my friend love it as much as I do.  It's one of my "favorite things."
