Summary: This stainless rice cooker is realy easy to clean if you use filter water to fill the inner and outer pot so that no minerals will deposit.I always use filter water when I cook so cleaning the outer pot is not a issue to me (I only have to wipe out the extra water on the outer pot after cooking). If you use tap water, you need to use vinegar (not detergent) to clean it, but it will still have some deposits.
Summary: For the health, we really like to buy one rice cooker with a stainless steel inner pot. So we found this one finally. After several tries, we can cook brown rice and it turns out OK. But when we tried to use it to steam vegetable, it is totally disaster. The green all turned to yellow. We also do not like the design - you have to add water between inner pot and outer shell. It is very difficult to clean up.
Summary: I bought this Sunpentown rice cooker in July 2008 at $108. After 9 months, a tiny hole was found on the bottom of the inner pot. The hole was big enough allowing liquid in and out during cooking. I had the pot replaced. However, 6 months later, same thing happened to the second inner pot. This rice cooker definitely has quality problem. I wish I didn't buy it. Now I end up with replacing the inner pot every several months or wasting $108 in 15 months.
