My shower heads are of Fa. Grohe and mistakenly I had bought the shower hoses from Hansgrohe, in assuming that this is the same company and the parts are compatible with each other. But they were not, because always stepped once more or less thick water jet out in the transition between hose and shower head. Now with the shower hoses of Fa. Grohe fix the problem! I just covered this plastic hose decided that sometimes roam the metal sheathed tubes in contact with the tile (sanding marks) left. The purchase was worth it, I can recommend this product with a clear conscience on.
