Quick and fine came packaged goods. The price is surprisingly affordable, Installation went smoothly. But the fit varies by about 1 mm in the optical domain. Therefore 1 point deduction. After a few days, it no longer falls on ..... The shower has no "inner life", as in my defective part. The water flows "simply by" what is without prejudice to the use value. In the original, a guide sleeve with spring valve was installed. All in all I am happy that my hair spray is functioning and no longer leaking again ..
