Product does not match the description (as of 10.29.2013)

Supplier: Amazon.com
In the product description of the faucet is described with EcoJoy but is delivered without the variant EcoJoy.
Unfortunately, this is not is also apparent from the listed Amazon SKU.
Decisive here are not mentioned at Amazon last three digits:
Standard: 32843 000
with EcoJoy: 32843 00E
This can be traced on the GROHE website if you are looking for the above items numbers.
The variants differ according to the enclosed exploded drawing (or the linked in the product information PDF "Technical Product Information") only in the aerator, so the outlet that contains the flow limiter, which linked to the Grohe website Exploded contain no difference.

After a replacement through Amazon brought no change assured me the friendly Amazon service employee that Amazon only performs a version, so the wrong thing.

The product itself does look and feel a good impression, but of course I have not tested it.

Thus the one star due to the fact that the product description and product do not fit together and I want to make other users by attention. For some, the water-saving effect may be an important product feature and would like to eliminate the difference subsequently would have at least another 20 (incl. Shipping) or more to invest in the appropriate spare parts.
