I bought the electric pressure cooker in the hopes it would make my life easier being able to delay cook roasts, beans etc. I am so dissappointed. the delay does not work right keep getting E4 error message that no one knows what it is all about. I threw the box away because I thought I was getting top of the line product--I cannot send it back. Now I'm stuck with a pressure cooker that will cook 20 minutes at a time with no delay timer. I am so SORRY I spent the money on this!!!!!SO NOT WASTE YOUR MONEY ON THIS COOKER!!!!!
