Great products. W A Y too many emails.

There does seem to be some improvement when the process is performed properly--but I find it very hard to devote too much time in a day to it, and have settled on doing 2 8-minute sessions four days in a row every three weeks. The results are nice, the process is somewhat burdensome.

I really like it!! I feel like it does help whiten my teeth. Only negative is that it’s messy and a little wasteful b/c it Keeps coming out after you’ve put it on your brush.

Hello!! Great customer service! Very prompt and genuine! Great quality products as well

I really like the product and the idea of it. However when the device comes in contact with my front teeth it sent a throbbing pain. Works ok if I hold it in my mouth and make sure it doesn't rest up against my teeth. The whitening process does work.
