Could do better
The fastest setting is "clean"' and that's not very vigorous. Other settings like: "white, polish, soft, massage, care" are slower and some include a pulse action- none of these are useful to the average person who just wants to brush teeth. Battery life is very good.  Brush heads are soft and not the most effective. If you get it on sale, it is worth if for a travel brush.
