Review (5/5): Great whitening system!
This is a great little system!! I purchased it for my daughter when she had her braces removed.She is prone to painful tooth sensitivity yet wanted her new straight teeth whitened. After reading up on and researching the GLO whitening system ,I decided to buy it for her(and for myself) We both are very happy with the (gradual but nearly instant) results!! We have white smiles and NO SENSITIVITY!! Both of my parents and my aunt are now going to purchase this system for themselves.
