1 received non-functional mixer (problem with the inverter) + default finish (2 halos at the brass-plated 38 ° C). So I exchanged. I also want to highlight the quality of service and speed of Amazon. After mounting the second mixer, functional but still a default nickel finish but less pronounced this time. After several showers the product meets my expectations in functional terms, it is a pity for the Grohe quality in terms of finishing is not waiting for you! The price difference (great price) can perhaps be explained like this? Perfect finishing Amateur, go your way.
