The iron can be operated up to a water hardness of 17 alone with tap water. Furthermore should you mix mains water 1 to 1 with distilled water. Pure distilled water must not be filled.
The filling opening for the water is large enough. However, no filler cup in delivery is what would have been expected at the high price actually.
The soleplate glides smoothly over any fabric and smooths without effort. Due to the narrow tip to reach even the most inaccessible places very well. The steam control on top of the device can be individually according to fabric type and degree heat set or you can use the Eccofunktion that automatically adjusts the steam for all types of fabric.
Very good, I also think the automatic shutdown of the device when the iron is placed vertically, and does not move 8 minutes. Or if it remains more than 30 seconds horizontally or tilted.
It merely needs to be moved to take the iron back in operation until the temperature indicator light turns solid.
There is an anti-drip system, what the escape of drops out of the sole prevented if the set temperature is too low.
The device still has an anti-scale cartridge is firmly installed to the water tank and may not be exchanged. The cleaning is very easy. Maximum amount of water fill, set maximum temperature, can heat up, hold over sink, pull the power plug and press Calc button. This is recommended to make every 2 weeks. Often with very hard water.
I think the value here is very good and recommend the iron you. In addition, it is made in Germany.
