Review title is Leaves Teeth Clean [SEP] I've used sonic toothbrushes before. I like the pink color of this. It comes with a travel case and extra brush heads. There are several different speeds/settings that you can use. As far as I can tell, there isn't a timer on it which would be nice. The bristles are pretty firm. I'm guessing maybe they are a medium. It does a good job of leaving my teeth clean.
