And the pressure setting is strong. 2 is good. 10 is too powerful for teeth cleaning. The whole set work great.
A little upset that the price went up $20 from the previous time I paid. Nevertheless, it is still a good product.
I have been using it for almost a month and I feel my teeth are cleaner than normal flossing, able to reach out to deeper areas of mouth, something that you cannot achieve by using the thread flossing. Good investment of money on this.
