Presto cookers are great...but this 4 qt. put a scare in me...put my chicken in ...pressure builds then I heard a sound looked and water shooting out of black button and handle button...turned off fire had to pry the black pressure button and handle button was jammed. I own an older Presto cooker and it is a wonderful cooker to own...guess I'm going to have to monitor these two new cookers just received.
