Have the product applied twice - can recognize and have no improvement, on the contrary, I felt that my teeth have discolored - all as in the manual! These plastic rails that you put into the hot water, I have to put on my hot teeth and then had real pain, that's why I find too dangerous !!! Did not really so extremely sensitive teeth but even then I think that that for such people is not suitable. If you have sensitive teeth, I advise you strongly depend on !!!
