Gentle pleasant sound
My husbands brush makes a very loud and harsh noise which put me off getting an electric toothbrush. But my new Suri toothbrush makes a very gentle pleasant sound - a bit like a buzzing bee! It cleans well too.
What put me of a little bit is the weight of the brush plus travel case. That is going to add quite a bit to my luggage compared to my old manual toothbrush with a flimsy plastic case. I guess part of the weight comes from that nifty function of the UV light cleaning - and I do love that!
Maybe also good to know for anybody comparing brushes: With the Suri you are still meant to make circling movements, probably because the head is very small and narrow and you need the circling to cover the teeth from top to bottom. So you can't just slide it along like some of the bigger electric brushes.
