The hose is not like the original spiral and therefore hangs like a "wet bag" on the side of the irrigator down. I have let myself be blinded by the pictures. If you look closer, it is found that this is outside of the wound intended for the hose Aussparrung. But no matter the function and also the advantage that you do not have to buy the same, a new center are clearly at an advantage. The enclosed assembly instructions I personally found well described (in particular times in a well-understandable and readable German). However, I have the impression that the amount of water through this hose comes a little less like the original, the pressure seems to be somewhat weakened. I assume that it is up to the non-spiral hose, because the pulses on the straight and longer hose replacement "lost". Luckily, you can increase the adjustment wheel at the side. Is just now at 5 and not as before on. 3
