I have used in the past for several years successively two models Braun WaterJet 300 that gave me any satisfaction. I had to replace last reached end of life, but this model seems to be available. I turned to the Oral-B Professional Care model, etc. This is a huge disappointment. First, it takes up more space. Then the WaterJet 300 was not particularly quiet, but it is much worse. Two switches including a well useless, which it takes two actions to stop the use and noise that comes with it, instead of above. Not convinced by the efficiency of the jet. I can not prove a malfunction of this article with no other identical models as comparator, but this model will soon end up in the trash and it will definitely help to get away from this dental jet brand .
