I'm happy with the Waterpik. I floss first, then use the waterpik. I can't believe how much stuff is left in my teeth after flossing. I'm so glad I invested in one.
It's great comes with additional attachments, it's nice and not real huge. Now I just need to remember to push the pause button before starting use so I'll stop spraying myself and the mirror! Haha
The regular pick that come standard will suffice. Remember to put the pic in your mouth before you press he. Iron or you'll get a mini shower. Don't make it too strong at First. Seems to work well
