Has some pros: A really practical piece of equipment! Because the pressure is so intense, the only setting I ever use is normal. My dentist informed me a very long time ago that if he used an irrigator to brush his teeth on a consistent basis, he would no longer need to practice dentistry. Various disadvantages: The volume of the container, once it has been fully cleaned, is only sufficient for one jaw. This means that additional fluid must be added. Because of this, I do not consider it to be a significant disadvantage. Outstanding value for the money spent on this product!
