Grind Free Teeth Whitening Gel with Tray

Works great, quick results. First couple of uses my gums were sensitive to it, but now I can do 45 minutes with no problem. I have had a lot of friends tell me my teeth are so white! I have ordered this product twice now.

what a joke. Hard to impossible to form the trays and get them to fit in the mouth. Uncomfortable and unpleasant to have in the mouth, and the solution is gross and foams out of your mouth. Tried multiple times using more or less solution, never was successful. Waste of money.

Read the directions. Some people complain the mouth piece doesn't fit. It will if you mold it to your teeth as directed. Others complain the light doesn't work. You have to take the batteries out and remove the little table covering the bottom if the battery compartment. It's a very small sticky tab. Put batteries back in + side up. This stuff is great and you get alot if it for the money

Tray is not comfortable and does not fit accordingly. Immediate difference when gel is used.

Works good but dont be too generous with the gel. Deff an easy setup and after the second time using it I saw a big difference

The light that came didn't work, it won't turn on. Also the emailed instructions are entirely different than the printed instructions included with it in terms of how often you can use the whitening gel, I don't know which one to believe.

Love it.

Seems to work well. Little uncomfortable due to the time it takes but still worth it.
