I couldn’t be any happier with my lil rice cooker. It’s so easy. 1 switch; On Off. I love the fill too marks on the inside of the pot (a little hard to read sometimes. The easiest way is just to fill a glass or something with water and pour to the appropriate line for the amount of water needed. Clean up is a breeze. No scraping, no sticking. I haven’t tried whole grain rice yet. The smallest model does not have a warmer.
