So, the packaging is simple but secure. The installation instructions are also German and comprehensible course. Installation is depending on the sink in my kitchen, complicated. The question whether assembly aids should be such as wrenches available I answer with yes. Many items that are to be mounted include small assembly aids such as wrenches because so ne pipe wrench but almost everyone. ATTENTION! The flexible connecting hoses "may" be too short for me the cold water connection could be screwed with great difficulty that one had to be careful not to overstretch the flexible hose. When these tubes were 2-3 cm longer there would not be a problem. The months of washing battery could also be simpler, because there is a problem with this semicircular disc of the assembly - kits which give the distance to the cold water supply decreased by approximately 1 cm. What might not be enough to be able to screw the cold water connection. The spindle screw on the nut is attached for attachment is not too long, you can screw on the bottom of the washing battery, but those with NEM screwdriver, the enclosed mother is a joke, because at some point will not get you more clever to turn on to. I have the old Monatge - Kit uses the semicircular disc, because that was further bent to fix the hoses. I've got the old mother used a mother the 3-4 cm. was longer / stronger, but took care of this spindle bolt. It has more space to unscrew. The enclosed mother is small and impractical, because it is at this point of attachment to very closely. I had managed only ne pipe wrench, but habs. The deduction of points are: The tap from the knobs is loose and wobbles, although the locking screw is fixed which should fix the faucet. The washing battery is fixed. Both knobs are a bit bulky and rotate slightly jerky, not rotate so easily. Let's see if that does not stop may try whether one brings in something dope, provided the knobs go down easily .... if at all. All in all, who without great luxury required times fast a battery wash, moved me the purchase due to a Lahma ****** s janitor, this product is an alternative, but as I said it should be remembered that the flexible connection hoses, at least the cold water connection, be too short "could", with me the distance of the connections (cold water connection right) probably have been just as adequate. The nozzle is OK, but I auswechselte through its own flexible nozzle.
