The supply of MMHesse came swiftly and neatly packaged for 73 per DHL package. The perfect 3500 from Wijas (Web: wijas.com.pl) can be connected to a 16 Amp normally hedged outlet. The power cord must, however, screw yourself with your device. We've installed it in the guest toilet at an ON-hose fitting, so no mixer! The wintry 7.5 degrees cold water comes in 1 liter in 15 seconds with 31 degrees from the tap. That's more than I had hoped for! The supplied aerator is mandatory and creates a pleasant soft spray like a shower head. FYI, you can download the German manual in Wijas as PDF. Quiescent current zero watts under load 3280 Watt.
For durability, I can not say anything yet, but the launch was smooth.
