“My device has a faulty lighting cable to connect to my iPhone so I had to whiten my teeth while sitting on the floor with it plugged into the wall. Have sent 3 emails to customer service without a response. Very disappointed.”
“Used the product diligently 2x a day for 30 minutes each session, for 2 weeks. No noticeable improvement. No, “whoa your teeth look whiter” or anything. Very disappointed. Won’t be buying again, nor recommending to friends.”
“Used religiously.. went without drinks that would discolor teeth.
Only thing Noticeably different, was tenderness in my gums.
Worthless and a waste of money”
