Autobrush u-shaped Electric Toothbrush

This is a new in box (never opened plastic wrapped) Autobrush toothbrush. I don’t know much about it. My daughter purchased one for her kids and one for herself and decided she didn’t want hers so she asked me to sell it for her. It is supposed to clean 27x better than a normal toothbrush. The last photo shown is a stock photo from their website
