I think it is working...... now. Let me explain. Foolish me I didnt realize that the peroxide gel wand needed to be turned at the bottom for the gel to come out. So the first few weeks I didn't see much progress. Now I'm getting the proper dose of gel. Also my teeth aren't so much yellowed as grey and I think that takes more time to see results. Overall, I'm happy.
