Did not work!
I used the product strictly as directed but it barely whitened my teet. I did use a color chart to make certain I could tell if there was a difference. The tubes are difficult to open without breaking the Q-tip like wand and the product in the quick stick type container squirts out after it finally comes out at all, wasting a good amount of the gel. I thought for certain I requested a return/refund but now cannot find this so I’ve wasted $60!
