This product was purchased by my wife. Have always ordered through dentist before. Dentist performed whitening study, teeth became 2 shades whiter when used as recommended. Continue to use approx. 3-4 times a month to maintain whitening. Since using these whitening strips have been complemented several times on teeth being white. Some sensitivity in the beginning but after initial use sensitivity lessened.
