I have seen this shower thermostat in a hardware store for 160 euros. I'm totally satisfied. I have all the fittings from Hansgrohe, which are already years old and this part is processed as usual high quality and can be precisely adjusted to the desired temperature. Energy efficient water consumption possible by the included additional units that can be installed. That the knobs are gray above, instead of chrome, does not bother me. IMPORTANT: It has the certificate of the DVGW (German Association for Gas and Water eV). We bought this shower thermostat for our new shower and without this certificate, it is not installed by a specialist company. Both sides can be rotated easily.
Conclusion: Favorable High-quality workmanship Does not heat even at high water temperatures Both sides can be easily turn Exact hot water setting possible Saves energy by using the supplied
Before we had a shower thermostat of Grohe (not the same as the company Hansgrohe is) bought what not had this certificate and had therefore return.
