Review (5/5): Good cleaning, good battery life, waterproof
It really makes life easier to carry and travel because of having a convinient bag. Its need to be charged depends on how muh u use. But I charged it once in a week. It has great vibrating power that making the cleaning pretty good. I feel very comfortable washing it too as it is waterproof but maybe vibration can b too strong for some ppl as it feels really strong for ur teeth. And if u r worrying about noise it doesn't really make loud noises.
