Review (5/5): It works fione
This product is safe for home applications, and it takes practice and patience especially if you are doing it alone. Overall it worked for me well, it helps save money on the dentist and time.
It removed build-up, I suggest watching a hoe to really get a good cleaning. Also good lighting and done.
They also give you a free one if you give them a review. I will gift this to a family member for the holidays.
