This was a gift for me as my previous unit (different brand) was inadvertently damaged by someone not knowing what they were doing. But, that's another story. This unit powered up and did fine for the initial test, but as it began to build pressure, I could hear the steam escaping from the pressure valve. Upon closer inspection, I noticed the quick release button was jammed. As I tried to work with it, the pressure valve actually popped out of the lid and onto the counter! Defective lid from the get go. So, I ordered the Mealthy brand. Almost 600 reviews, and rated five stars.
