I gave this product 4 stars because I started using it for a week. I already saw an improvement of whitening of my teeth but after the 21 days I will know if my teeth are as white as they show in the pictures of these people; so I will give another review later on.

I'm using this daily and my teeth are definitely getting whiter. I had a hard time finding a place to connect it. It shows on the diagram that it can be connected to your phone, but that didn't work on my phone. I found another place by my computer.

I can see a difference in the initial treatments. And for the most part, my gums are not sensitive.
