I got the NHS-10 model and it's the perfect size. I can make just one cup at a time (their cup measurement, which is equivalent to ~2/3 US measuring cups) or up to 6, and the rice comes out perfect without practically any work.
Good quality product, good rice. I didn't think I'd notice a difference, but I did. This rice cooker makes better rice than my previous one from a different brand.
I was given a Zojirushi rice cooker 28 years ago at my wedding shower. I was bummed when it finally crapped out and tried a different brand as a replacement and it was terrible. I found the exact same style of Zojirushi but with a modern facelift and it is perfect. All I need is the little click if that button and I know my rice is going to be perfect. I look forward to another 28+ years with this one. It's a simple, sturdy and reliable design that is so hard to come by in kitchen appliances, and I am glad this type of cooker is still available today. Thanks for not discontinuing.
