Product is easy to use and effective!

I felt the teeth whitening gel vials were less--used one once and that was it. It seems thicker--maybe out of date?

I have been using this product for about 2 years. I did the accelerated treatment in my dentist's office before purchasing the glo system. I don't feel like it makes that much difference, and it does not get along the gum line well. I feel like the top of my upper and bottom of my lowers stay somewhat yellow. I use is every 6 months for 6 days.

White as much as I thought it would not purchase again

If I don’t get better results, I won’t continue using this product.
