Question: Any estimates of how many servings of steamed veggies are possible? I want to buy this but worry the steamer tray may be too small for a family meal.
Document: This is a wonderful appliance. Cooking is fast and easy. I have cooked everything from veggies to fish in the steamer while still having perfect rice in the tub. Cleaning is a breeze. A complete meal ready to go. A perfect item to have in a small apartment or  college dorm where cook space is a challenge.
I don't use it just for rice. I used it for any steamed meals that I can cook with my rice. Try some chicken breast on the included tray, and a mix of soy sauce, chili oil, lime and some sesame seed and you have a great basic meal that, in the right portion, is healthy. I've even done steaming of my pork buns or have even used this as a way to cook my hot dogs.
I had this rice cooker before (for almost 10 years), but the pot got bent and wouldn't sit properly in the outer container, so the appliance kept popping over to the "keep warm" function and wouldn't cook. I looked at many other models before replacing it with the exact same model. It cooks my rice perfectly, every time. It's also easy to steam veggies, though I wish the capacity were a bit larger (family of 6).
This rice cooker made beautiful, delicious rice the very first time I used it. Having lived in Japan for four years, I know what rice should be like. It was perfect. I am a college student, and with this rice cooker, I am creating healthy, inexpensive meals since the steamer tray means I can make delicious, healthy veggies while I make rice. Plus I love being able to start the rice, and wander off to do other things.
Zojirushi NHS-18 10-Cup Rice Cooker/Steamer & WarmerI say its ok. It makes too many rules to make rice and to me the rice is watery. You can't put the rice in the rice maker pot and drain the rice before turning the rice maker on. you have to use their measure cup, use a separate bowl, use the measure inside the pot for water amount, the glass lid is heavy, slippery and hard to clean. I expected more simple instructions and better steamed rice.
This is a good machine for the price, considering it is also a steamer, and a good one. If all you want is to make rice, any cheaper rice cooker will do. This one's for people who like to make everything in their rice cooker (which is possible in cheaper rice cookers, only there's no rack so you can't steam vegies as easily).Just wanted to respond to what Drew wrote about not having to rinse rice.
I have even steamed jewelry as a final step in the cleaning process! This allows me to get really creative in a healthful way, in no time! I plan on giving this cooker to my son when he goes off to college and I will  buy the larger 10 cup unit.
This is an upgrade of a smaller capacity Zojirushi I bought through Amazon a year or two ago. I loved it, and the only reason I am replacing it is that my brother loved it as well. Since we have a family of six and eat rice every day, I figured I would just buy a bigger one and give him the smaller. He is happy, I am happy. My husband is Thai, so we cook only Jasmine rice.
We've only used this to steam veggies, but we use it multiple times each week and it's great! The directions are vague and it did take a few uses to figure out how to make awesome steamed veggies, but once we did we began loving it. I recommend using your own judgement by looking at the color of the veggies to see when they're done because the preset cooking times (however those are measured) either under or over cook the veggies.
After my microwave with the convenient rice button was replaced I was left without a means to cook rice effectively and could not perfect it on the stovetop. Not good when your family loves rice! A friend told me how much she loves her rice cooker, Zojirushi 6 Cup and after reading some reviews I purchased it. The 10 cup was not available on Amazon at the time, boy I wish it was! I have made so many great tasting dishes in the last 3 months!
Answer: We use it for 12oz of green beans, broccoli, asparagus, etc. often; and we have put up to a pound of veggies in it, which just requires that you stir them half way through so that they all cook evenly.  We are a family of four who eat a protein, veggie, and starch for each meal, and this steamer is perfect for our family for veggies every night.  When we have guests and have to make 2 separate batches, each batch only takes 10-12 minutes and so it isn't a problem for us.
