I finally broke down and bought a Zojirushi water warmer for my tea. Having just microwaved water in a pyrex measuring bowl for years I decided it would be nice to make tea drinking a bit easier and quicker. I am trying to give up soda and I wanted to remove the temptation of instant gratification of just grabbing the 2 liter from the fridge. So now having sunk all this money in this fancy tea kettle my questions are for anybody who might have one also; Do these things require any special handling/maintenance and more importantly are they reliable?
