This is my second one. Have had one of these since 2009 (+ or -). I always get great dental exams since starting. And have made things in my mouth better.
I bought it about two weeks ago and use the head that's best for those with advanced gum disease. I am very happy to say that the pulse is powerful, the head can be turned easily to reach both sides of teeth, and I'm confident that the Pik is doing its job.
