I purchased this toothbrush in December and unfortunately did not open the box until now. My old sonicare toothbrush's on and off button is finally giving out. Anyways, super excited to have functionality and cuteness combined, just to unpack this item and it does not work. Does not even charge. Completely defect and wasted money. Seller did not respond to my complaint email. Very disappointed in seller, and Walmart, too, for representing a company so customer unfriendly. Lesson learned, unpack and try product out immediately!
