First, the sending of a total of 9 days from purchase lasted unusually long. This is probably due to the declaration of the letter Warensendung. After unpacking, unfortunately I had to realize that the picture at Amazon disagreed with the delivered goods. The white plastic connector for connection to the sewage system did not exist, the illustrated hose clamps (tighten with screwdriver) were replaced by cheaper hose clamps made of steel wire. The tube, however, was fine, but not the whole package is obtained that one has acquired on the Amazom platform. Thus not ztu recommend!
