Qualitatively, there is at this pipe nothing to complain about. This has also fitted me up perfectly, but I really had with the lower connection problems. The tube has the connection to the nozzle a very small diameter (about 30mm). Although I already had a new adjustable universal nozzle with screw cap, I could not install them because the pipe diameter was just too small below. I had to order me another universal nozzle, which was suitable for diameters from 30mm and even these die just yet so fit. She had to be adjusted with great force to the smallest possible diameter - that was really OK!
Suggestion: below a 2 mm diameter and grüßeren already fits virtually any nozzle on it!
The seller even replied to my requests very prompt and courteous. What helped it but nothing, a new purchase of the nozzle was inevitable in this tube.
