After many years of low-Hahn in tenement I have decided to change this. Loud noises flow and cheap processing were not good for each day start. In any case, this basin mixer is their money more than value. In 20 minutes installed - the good illustrated description leaves no wish unfulfilled. The first turn on and ... and ... the water is doing what it is supposed ... running from the tap without the top mentioned noise. The lever is smooth and you can see the Grohe what understanding of their products. All in all ... and especially for the price absolutely recommendable.
