Fast whitening
I ordered these for my young adult daughter who was wanting to whiten her teeth before school photos. It works and it works fast. The only issue she encountered was that if she left them on too long, it made her teeth more sensitive. Other than that, she was very pleased with the results and I could even tell her teeth were whiter. For the price, it is a great deal more affordable than the dentist whitening.
