I've had 2 of these forever. They have outlasted my regular sonic brush. Since it is travel it is smaller, but has tons of power.

Really enjoy the clean feeling and polished feeling that my teeth have after using this brush. I find my teeth are happy.

Have two daughters who are flight attendants and I travel often. These are the best. Cute, small, and allow me to travel with the closest thing to my electric toothbrush. Everyone got one in their stockinged this year! Big hit!
