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.
I bought this to replace the original one bought in 1986. It finally died, but it worked great. Now this new one works even better as it hold more liquid and has more ability to increase the force of the liquid. Cleans between each tooth and leaves your mouth fresh and clean.
I'm older and this is making the dental process much easier. Takes a little practice so you don't have to clean your mirror all the time but gets the job done very well.
