Bought this because I was experiencing some gum soreness and bleeding when I was brushing my teeth. I started using this and within a week the soreness was diminished and the bleeding had stopped. I'm unable to floss, so this was a true blessing! YEAH! I use this at least once, sometimes twice a day.
I have only had this product for a bit over two weeks but, so far, I am real happy with it. My teeth feel so much cleaner than they did with just flossing. I like the size of the product as it doesn't take up much space on the counter and can easily be stored on a shelf. My only complaint is that I wish that the On and Off switches were not so close together and that they were a little easier to depress.
This is the third Waterpik product that I have purchased over many years and when my last WP-360 wore out I liked it so much that I replaced it with another. Great product overall at the right price!
