“Although pricey, this is the best whitener I've ever used! I received my first tube free with the purchase of an electric tooth brush and immediately noticed my teeth getting whiter. After I completed the tube, I decided to try a less expensive whitener from Wal-Mart and noticed that my teeth were turning yellow again: I drink a lot of coffee and red wine! So regardless of the price ($30 with tax) I'm back to using the Go Smile whitener since it's the only one that really works!”
