This works very well, and I would purchase it again. My only complaint is that if water is left in the reservoir, it leaks out, leaving the counter, and electrical cord soaked.
Bought this recently at the direction of my dentist, who suggested this brand and model versus the rechargeable one.. Like that I can adjust the flow, as you go so you don't have to turn off. Tubing a bit stiff right now so have to bring device close to sink -
