Since I now have a bit longer this irrigator in use can I make an initial conclusion. The optics of this oral irrigator is very appealing. The accessories are housed neatly in the lid of the water tank. Fill with water and handling very well. The radiant intensity can be adjusted in 10 steps. So for every "mouth shower type" the correct strength is. By pressing on the handle of the beam can be turned off immediately. A beautiful, vibrant, uniform jet massages the gums and cleans the teeth and interdental spaces. We are very satisfied and would recommend this irrigator.
