Scam! After seeing some good reviews and all their advertisement I thought I would try the teeth whitening kit. I tried it for 2 weeks and took before and after pictures. There’s not even a slight difference!!!! The whole company is a scam and every good review must be fake as the product clearly does not work. I don’t understand how the company has not been shut down or sued for false advertising. Save your money and just go to the dentist for a teeth whitening these products and not worth the stress and waste of time and money DO NOT BUY!!!!
