I be not expect much for $ 15 but it do exactly what its suppose to do . I cook whole grain brown rice in it almost everyday . it only take a day or two to figure out my rice to water ratio to get it exactly the way I want it . one scoop be perfect for one medium size serve of brown rice . the thing just work and do exactly what it be suppose to do . I give it only 4 star because it do feel a bit cheap but since it just sit on my counter no worry . everything clean up easy . Great for a single person who do not like to cook . this be much easier than have to watch a pot boil rice . it will crisp on the bottom a little bit if you leave it on keep warm for 15 minute like they say . but that bother I not at all . like another poster say you can stir after it finish cooking , which be what I use to do with pot cook brown rice but I like the set it and forget aspect of this so I do not bother . could not be any more satisfied with a $ 15 rice cooker .
