The cost of the aerator / aerator alone are much too high. Never again a water tap with a special form for the aerator !!! 19, - for this part is just too much !! In addition: This part is destroyed during removal and must be replaced, since the mechanism (plastic pen) breaks for the special key. Then the bubbler can the next time with this great code may no longer be expanded and cracked the lever out. More expensive faucet with aberration and high maintenance costs. Round quality aerators I min. 3 x descale before they must be replaced.
