I have been using pressure cookers all of my life. I love them. They take a tiny bit of common sense. I actually had the exact Electric Presto models shown in the picture, but the nonstick finish started flaking off the very first time I used it. So I took it back. Presto has been around a lot longer than Instant Pot. I have had one of their uncoated completely manual aluminum models for decades.
I purchased a larger automatic electric models from Costco a couple of years ago; it is also not an Instant Pot. It has been fine and is almost foolproof as well. I think that the problem with automatic units, if you want to call it a problem, is that they kind of “insulate” one from the actual process that is taking place.
I am extremely skeptical of the sequence of events told by the unfortunate lady. The identical Presto electric pressure cooker that I owned had both the blue pressure indicator that she mentioned, a pressure relief valve, and a lock that if you had screwed the top all the way on, would not allow you to take it off until the pressure was released. She had to do several things wrong to get hot soup all over herself.
It is impossible to make anything completely idiot proof. How many people have managed to take the door off their microwave, tape the safety switch down, turn it on and then stick their head inside the open compartment to make sure it was actually working? We will probably never know.
It looks like the autocorrect feature on my tablet is acting up again. Sorry.
