Question: What is the inside of the cover made of?  I'm concerned about steam heating plastic and infusing the rice with it.
Document: Few months into use and working perfect. This thing makes great steamed veggies while the rice is cooking, both finishing at same time. Great stainless pots inside and well made overall.
I searched on and off for several days before I could find this rice maker - one with a stainless steel cooking surface. The 7 cup maker is a bit larger than I require, but not a problem. Since its arrival I've made sushi several times (nishiki rice), brown rice, calrose rice and jasmine rice (in coconut milk instead of water. )I'm very pleased. It cleans easily and I LOVE the fact that the power cord detaches.
My rice comes out as good as my old expensive rice cooker. Reason to buy stainless steel rice cooker it'll last longer more healthier than nonstick rice cooker. Nonstick rice cooker can becomes rust if it is scratch from the inside.
This little cooker just keeps on cooking after many months of use. Love the stainless inside pan as it do wear out.
I was looking for an automatic rice cooker that was all stainless steel inside. This is it. It cooks rice well, whether it is brown rice(which I mostly eat) or white or any other. I gave it 4 stars because the top insert  keeps popping out which is quite annoying. Im willing to deal with it because I will not have any other unit if it is not all stainless steel. Other than that, everything is good. I like the fact that it is all stainless steel.
Got this for my mother for Christmas and had to return it and made her wait for me to purchase a different rice cooker. Waste of time. The inner pan overcooks the rice on the outside.
Thank goodness I bought this for my mother...we have had YEARS of undercooked, overcooked, burnt and sticky rice made on the stove. This appliance makes excellent brown and white rice. BUY IT -- even if you only use it a few times a month.
I have looked for quite awhile for a stainless steel cooker to cook rice. They are not in any of my local stores, and I live in a big city. It is just perfect. If the rice sticks on the bottom, I just soak it for a few hours in soapy water and it will clean very easily. I love knowing that I am not eating any Teflon or plastic residue! !
Whatever rice adheres to the bottom of the pot is easily removed after brief soaking.The Oyama also has a removeable plastic condensation collector that snaps on back of the hinge, which must be removed and cleaned after each use. That's not a biggie, but it's the kind of part that is easy to lose.I've posted photos of the Oyama to help illustrate all of the issues.
we want to find a stainless pot rice cooker. It takes about 20 mins to cook the rice, and it tastes better than our old cooker. It's convenient to have a steam rack, i use it to have tofu, egg steamed with the rice.
Answer: I never cook in plastic so I was concerned as well when doing my research. The insert that the rice cooks in is stainless, as well as the inside cooking unit and inside lid.
