Yes, the kettle can also be used as a tea kettle, as it is classified as a tea kettle type. After boiling water, you can therefore also use it to make tea. It also has an automatic switch-off function, which makes it safe to use.
Yes, that's the case. The automatic switch-off only takes place when the water is boiling properly, i.e. +/- 100 degrees Celsius, which is a disadvantage. I'm still satisfied because it's easy to pour into a cup or teapot and the water heats up faster than in a pan.
