Easy to use
I got this just to try it and without much expectations but i am now incorporating it in my brushing routine. My teeth isn't blindingly white, but i can see little changes. It's quite easy to use, just wet your brush and lightly dip in the powder and rinse when done, you dont need a lot so i can see this lasting for a while. I like that it is  affordable and easy to use
