It will die on you.
This thing is a dud.  After usi g for a few weeks the power on it gets week.  I recharged it multiple times but the power is still  week and sometimes it turns off on me.  Half the time I turn it on it doesn't even vibrate but makes a different noise and I have to take the brush out and put it back then it will turn on.  This knock off is not worth it.  Stick with the name brand one.
