very easy to use, very effective. I like how it covers my whole teeth front and back. nice big size.
I have used other teeth whitening products, but this one is the best so far. I used it for about 2 weeks and it really did whitened my teeth! It was amazing to see the color change of my teeth
It tastes good unlike other teeth whitening products tasted awful to me. I used it for about 3 times, I guess I have to keep using it more for dramatic change
