Don't waste your money, I already did it for the both of us.
[[VIDEOID:36d398a428ca5f77cd14581c8d0613df]] This is the second flosser. The first  flosser's  knob to adjust the strength for the water pressure did not work. Also, one of the attachments came broken. I returned it and was sent new one. Now this time, it really has outdone itself.  Water comes out of every hole and crevice possible, even the charging port! I've attached a video of the foolishness. I'm send this wreck back. If there was a way to give this a zero I would.
