So far I had always cheap shower thermostat used from the hardware store. Unfortunately, these were due to the plastic parts difficult to disassemble with calcification and therefore unusable. Have long wondered wanted and now the Hansgrohe Ecostat 1001 SL Thermostatic mixer bought. All the main parts are made of brass (hence the higher price), control is very fast and accurate. Manual is also made easy and understandable. I think they are very good and it can only recommend!
