It was a huge trendy item with moms that were shit cooks. Very over hyped item by people who will spend twice the time making something they couldore easily make in a dutch oven or just regular stock pot.
That said, if you're actually wanting specific pressure cooker functions it's handy, I guess.
My experience is almost everything I've tried from other people was shit and the wrong tool. I've had hood pressure cookereats, nit not from the type of cook that is like omg instant pot.
Myself, it's been handy at times for beans, nut I rarely use it outside of an easy pot luck warmer.
Mt girlfriend uses it for hard boiled eggs and cooking from frozen when we forget to thaw meat for the dog.
Had even tried yogurt and it was worse than my 15 dollar yogurt warmer.
Overall, have never been impressed and even the few things it's serviceable for its not exactly necessary. It's like many gadgets that try to be all in one and becomes mediocre at all.
Oh yeah, boiling the hell out of bones to make a stock and not have to worry about evaporation. That's the one thing I really like it for.
