The replacement hose arrived on time and also has a good quality. But what I want to draw attention is this: I bought my RUSSKA Irrigatorset in 2001. At that time, the tube had an internal diameter of 0.8 cm. The now supplied hose only has an inner diameter of 0.6 cm, so I can not install it on my Irrigator. So if you use a very old vessel, you will buy the same a new set and you save a lot of hassles.
