I have an Instant Pot it and it cooks a chicken the same time as you did in your stove top one. I was scared of it at first, as a kid I was terrified of mum's pressure cooker I always thought it would one day explode. I have gone back to my slow cooker as I can put everything in it in the morning then just leave it all day. Instant Pot now in the gadget graveyard shedI've got 3 different sizes of pressure cooker - 3l, 6l & 7l but can only use one at a time as they all use the same lid but means I can use the best sized one for what I want to cook. Always take the 3l one away in the MH with us when we go away, particularly in the colder weather.
At home I mainly use it to cook pulses and stews.
I've got a small Pressure King Pro but not that impressed with it - glad I bought it second hand and didn't pay full price for it! Much prefer my hob ones.
