I have used this product 4 times since receiving it. The rice cooked perfectly each time. Was also very easy to clean the rice steamer. HOWEVER - the inner steel cavity in the base has developed rust spots and patches - within 3 uses!!!!! Very disappointed with this poor quality material/workmanship. I do not want to be cooking with a rusted product. The rust spots and patches are not easy to remove. For a product that costs so much more than others and claims to be made of stainless steel of high quality, it is not a worthwhile investment at all. I am glad I ordered the smaller size of this product. I will be returning this after speaking with customer service.
