1. With regard to quality / durability / robustness and the like, so I just can not allow final opinion, I simply the expertise but also the long-term experience is lacking (!). I did not feel as if Baumarkt hoses less adequately. Rather, and this brings us to ...
2. ... I was afraid even a "breaking" of the hose when laying because it is really designed incredibly stiff. For me no automatic sign of value (a tube of such material would probably want to use no outside), but mainly an annoyance that a reasonable, ie to your own setup appealing laying prevented.
3. The positive quoted "guidance" is a loveless diagonally patterned A4 sheet with a drawing, the more confused because sometimes helps. It lacks any explanation. The saw itself the Customer so, with whom I phoned then and the many self not immediately understood.
4. Why I buy the hose at all? Because it's the only one with whom you his lifelong Aqua-Stop warranty on the part of Siemens (and probably Bosch) reserves. So far, so understandable. On the other hand I would like to see but a wider choice. One gets only 2.5 meters, that's it. Makes me a total of 4 meters inlet, 3 meters would have been quite sufficient. As a result, see 2 that the tube now cross winds through the bathroom.
Well !!!
