I buy this cooker in May 2011 , and have use it at least twice a week ever since . within 2 month , the steamer tray become very warped . in addition , the cooker make a huge mess every time i use it . it do not seem to do it as bad when cooking white rice , but since I cook mostly brown rice and quinoa , it get sticky watery mess all over the place . I think we could deal with it , but my counter be get stain ! Time to replace the cooker !
