Basically, this device good oral hygiene (cleaning effect of the toothbrush and oral irrigator, handling), BUT !!! The durability of the pressure hose of the irrigator is appalling: This is my third device of this kind, and the quality of the tube appears to decrease gradually. The first device about 8 years (ok, corresponds approximately to the lifetime of the battery in the electric toothbrush, the second device about 4 years (for a branded product already unacceptable). With the current device the hose after almost 2 broken years, that fortunately the period of guarantee. This can not well be. Or is there system behind it? It is but give manufacturers of plastic tubes that do not become brittle in such a short time. On the second unit I have, incidentally, the holder of the irrigator disassembled, what cunning and trickery already possible, the tube cut off a piece, and assembled the whole thing again. But since the problem is the Materialsprödigkeit, it did not take long, and it was again a hole in it. Then I I also dismantled the basic unit (unfortunately you need for a long narrow Torx screwdriver with bits will not get you into the narrow screw holes), to replace the hose completely by another (from the chemical laboratory trading). Unfortunately, while the very measly piece is broken off at the pump. After that everything was for the garbage, even the useful per se toothbrush, because that was not compatible with the charging station of the third device. Conclusion: The quality manager of Brown / Procter & Gamble should firstly secondly times pull its development engineers and the suppliers of the pressure hose ears long. Last but not least: If the warranty repair does not extend the shelf life of the device at least 6 years, was certainly the last B Oral Center, which I bought. Addendum: The Garantierreparatur has extended by 1.5 years just the life. The pressure hose is Gelumpe and outrageous - with all due respect. Skillful Handyman Grab (the Internet mail order, is also on Amazon) for a few euros a (preferably preformed) spare tube of a different material (mine is now made of transparent light blue plastic). When withdrawing and re-plugging onto the connection piece absolutely careful. Heating with a hair dryer facilitates.
