Excellent, quick, and convenient! I love my tea and pressed coffee and this is the perfect item to get it quickly! I have owned my electric kettle for over 9 years and have referred friends to buy it. They also loveit and could never go back to stove-top kettles again. It is also an easy way to get a head start on boiling water for recipes. I put mine in the kettle first, then pop in in the pot when ready.
