Review (5/5): Faster and more fun
I use this every day. It is more fun than using a normal brush. I have some overlapping teeth and it gets into those crevices nicely. I don't need to use a metal dental pick as often to chip away the plaque. You'll use more toothpaste because the vibration causes it to leave the brush.
I recommend buying the extra heads when you buy this. Last time I needed heads they weren't available any more.
