Despite a restriction I'd buy this faucet again

I have this Grohe sink mixer now already for half a year in use - so I can report from practice. (During this time, the valve has become the way cheaper, I paid another 190 euro for it.)
The faucet is stylish and modern, makes a noble, high-quality impression, evaluates undoubtedly my somewhat in the older sink to. The adjustment lever: to Wasseraufdrehen tilt to the right, for hot-cold front or back. All smooth and solid. German engineering flat.
The installation resulted from an expert, he needed 20 minutes and stressed he did not look it. But that even a layman installed? No, I can not imagine, only a highly talented handyman should trust that.
For Use: The high spout is swiveling and very practical. No problem, topsy see a watering can or a bucket or big pot. What in the kitchen's otherwise rather makes problems. The front portion of the outlet, about 4 centimeters long, can be easily packed and pulled out. This part, called aerator is then free to move with its about 40 cm long, flexible cable. Thus, the water jet can be used in places to which one otherwise would need a cloth. very convenient! After use, the whole purring again obediently back into its housing.
Now comes the caveat: let the water run without the aerator pull out, the beam after a while becomes thinner and eventually he splashes quite powerless. What probably because of the fact that the water must first pass through the under sink hanging hose. It then pulls the aerator, the beam gets back a little more oomph. Because it is not as powerful as bubbles from a "normal" tap, it already takes much longer to tap a larger amount of water. But well, you get used to it. Perhaps the Grohe design team should think about the problem.
