indeed universal and quickly installed ...

As already indicated in the product description, the filling valve is actually suitable for almost every exposed cisterns. For me, the fill valve comes in a 9ft (NoName) -Spülkasten used. Capacity can be quickly and easily adjusted continuously. The installation was done within a few seconds. Old filling valve out, new in, finished. Quieter than the old fill valve is all. However, one should note that no seals were (in my case) when. The fact that I could continue to use the old, however, this was not a problem.
Conclusion: price / performance ratio! Full marks - Delivery as usual quickly and easily.
