Query: Can't live without it!

This is the second Zojirushi boiler I've owned. The first one was on day & night for 10 years so I wasn't the least bit concerned about replacing it with the same brand and similar model. I first saw one of these while visiting friends in Hong Kong -- everyone there keeps one on their counter for instant hot water for tea or soup. I love it and so will you.
