I prefer a real pressure cooker.
I've never had a problem regulating heat.
When the cooker reaches the vent stage, I set the temperature to 3 on my 'stove.'
It's faster than an IP.
It requires very little attention.
I can tell what it's doing by the sound.
From a previous review:
"The insert is easy to clean.
It requires about as much cleaning time as the entire stove-top pressure cooker.
Then there's the lid. The four piece lid.
Then the pressure cooker body, the cord and the counter-top.
Something else that I found irritating.
When it came time to pour the PC'd chiles and some of the other ingredients into the blender, it required fiddling with pot-holders to handle the insert, where the stove-up PC requires simply grabbing the handles and pouring.
The clean-up and fiddling around as well as other differences required an additional 15-20 minutes compared to using the stove-top PC.
Anyway, just my honest assessment at this point."
