The Ultra Plus is a great countertop water flosser. It cleans in between the teeth and along the gum line really well. The slider switch on the handle to the water flow works well. The rotating nozzle is simple to use and the 10 pressure settings gives plenty of choice. I could happily use the Waterpik Ultra Plus on a daily basis, but my pick would be the Waterpik Ultra Professional.
