Familiar Grohe quality with potential for improvement

I tried first in 2 hardware stores a replacement for my leaky sink faucet to get. But unfortunately seem DIY nowadays only to lead their cheap store brands. Because I wanted a quality faucet, I then decided to go for an order of this Grohe faucet here on Amazon, although I would have preferred to see them first in natura.
First the positive: the valve is of the usual good quality Grohe, the ceramic mixer is very smooth.
What bothers me a bit: the fitting is somewhat clunky and bulky, but that seems to be modern well today. Probably not suitable for small kitchens. But that's a matter of taste. I mention this only because one can not see from the photo.
Jenachdem how to use a supplied disc, the spout can be rigid or swiveling using (150 degrees). The swivel range is not symmetrical, so I had to install the faucet at a slight angle (approximately 45 degrees rotated), otherwise I could have not pivot on the draining board. Too bad that Grohe attaches no second wheel, with which the outlet could swivel 360 degrees. So a slice would be a dime items.
The connections are not marked, which for hot and cold water for which is. The sketch in the guide is saying, and I had it connected first wrong promptly (Murphy's Law). A red and a blue tape should actually priced not worthy to be in such a fitting. Manufacturers have actually learned nothing in the last 100 years, or it really comes today in the production of every penny to?

Due to the asymmetric pivot range and the unmarked ports I subtract a star.
