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 -
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.
