Wish I had discovered the 30 Second Smile years ago.
I was given this item as a gift about 18 months ago.  I was a bit dubious because I had used other electric toothbrushes in the past and was generally unimpressed by them.  Boy, was I in for a surprise!  This unit has performed flawlessly since I first received it, it is very clean, neat and fast to use and, best of all, leaves my teeth and gums feeling remarkably clean. It seems that the 30 second smile gets out food that I've been unable to get to with my regular brush, thereby reducing plaque build up.  In fact, at my first 6-month teeth cleaning after beginning to use the 30 Second Smile, my dentist asked if I was doing anything different because there was less plaque build-up then she was used to seeing in my mouth.  I believe she ordered one for herself shortly after.
