I have purchase two of these cooker . when they work , they be so convenient - perfect for small batch of rice , oatmeal -lrb- do not use milk - it will bubble up and make a mess -rrb- , quinoa , etc. . only problem , they just do not last very long . the first one I have only last for a couple of batch and the second one last a couple of month . I keep buy they because they be the only small rice cooker that I have find on Amazon , and the price be reasonable . as long as Amazon keep take my return , I guess I 'll keep buy this cooker even though it be a bit of a hassle when they stop work .
