Bests & Worsts Reviews from Amazon

My relatives have an equivalent Zojirushi model. The only difference is this one only has a 6 hour delay whereas the Zojirushi has a longer delay setting. It actually seems like the Panasonic insulates and holds the heat in better than the Zojirushi as it doesn't seem to reheat as often. I'm sure it would save a few pennies in power costs if I could delay it a little longer while I'm away at work all day but it isn't worth almost double the price to get that. That's the only reason for the 4 stars instead of 5. I actually like and prefer the nonstick interior and unless you've got hard water, you don't have to clean it as often as they suggest. It's over a month for mine being used every day and it doesn't look any different than when I bought it. I figure I'll clean it with lemon juice every other month. Note that you don't have to buy the special cleaning solution. Make your own citric acid with a half cup of lemon juice concentrate mixed in with the water and then run it through the cleaning cycle. If you use fresh lemons make sure you get the pulp out. Update 3 years later in 2012: Still working great. I clean it about twice a year as our water is already softened and we filter it before pouring into the boiler. One time after not running a cleaning cycle for over a year it stopped working in that it couldn't tell when to stop heating and overheated. I ran it through a cleaning cycle and it was fine after that. I suspect the thermometer had some calcium or other deposits built up on it.
