I do not regret my decision:
+ Solid construction of all components, including the tubes!
+ Very good dimensional accuracy of all parts
+ Smooth, dense pressing by hand
+ Very good chroming
+ Optimally adjustable immersion tube
+ Normal sized drain pipe (enter the pipe in the wall terminal nor a depth of approximately 5 cm)
+ Easy cleaning of the siphon through access from below
The installation itself is done in minutes. What is needed is possibly only a hacksaw and some sandpaper if diving or drain pipe is too long.
highly recommended
