Bought over the last 8 years 3 Mundduschen Braun, the last Proffesional Care Water Jet. All three devices showed despite careful handling shortly after the warranty period is always the same error: the hose breaks about 4 to 6 centimeters after emerging from the housing and the oral irrigator is no longer usable. Anyone googling a bit, will see that the net is full of such errors at Braun Oral Irrigators. Brown is the lack known for years. Perhaps interested should employ these devices sometimes with "planned obsolescence", simply Find out! I can because of this negative experience only advise against the purchase of Braun Oral Irrigators all! Unfortunately, you can not assign 0 stars here!
