After unpacking, as requested 2 times cooked. Then once cooked 3 different teas, all tasted the same. After plastic. Then I cooked 5 times clear water completely. Also smelled the last fill / tasted much like plastic. Whether it was because of the hot Plasikboden the kettle, or the filter has no longer interests me. When "keeping warm" runs some of the water repeatedly through the tea. He is after 30min then already 5 times and brewed according bitter. -> Return to sender
