Great Results.
I have tried other teeth whiteners but they caused so much pain that I couldn't use them.  This product has offered me excellent results without all the sensitivity pain.  I don't have to use daily or I will use every other day so it doesn't cause the sensitivity.  It really gives great whitening results and is really easy to use. Provides an even finish with being gel.  Highly recommend. I just got the 15% and looking forward to a quicker whitening time.  The toothpaste is excellent as well.
