I bought one and had trouble getting it to come up to pressure every time. Sometimes it would and sometimes it wouldn't. I never knew when it was going to decide to work. Murphy's Law mandated that it was only with the most expensive, hard-to-cook-otherwise ingredients like babyback ribs.
I troubleshooted with the warranty department, and after many tests, they reluctantly sent me a new one. The new one started doing the same thing. I got frustrated and gave it away.
I liked using it for soups. If I knew I could get one that didn't have any problems, I probably wouldn't. I'm retired and have a bunch of time and pots/pans to use. Like alot of gadgets, there is alot of extra cleanup required... now I'm wondering about an air fryer. LOL!
