Very good quality, high-quality cable, sturdy plastic parts for the cap and handle that you can tell will last for years.
Indicator light and automatic shut-off are included, and nice red color on the metallic body with embossed brand logo to prevent fading.
The reason I bought it is because I wanted to move away from completely Chinese-made products with leaks, etc.
What impressed me is that it doesn't take up much space in terms of dimensions, even though it is 1.7 liters.

It lasted 4 years and then broke on the lid! I consider it to be well built and functioning well. I won't comment on the salts because I don't believe the kettle is to blame, it's the water's fault. As for the major downsides, the excessive noise when heating the water and the speed at which it does it... At night, in silence, it might be heard throughout the entire apartment building.
