Question: What psi does this cook at?
Document: It's marvelous - everything a Pressure Cooker should be!!! It's smaller and easier to cook with and handle.
I never knew a pot could cook like this one does. And the price was great.
Yes, I would recommend to anyone wanting to cook a good meal in a hurry. No slow cooker for me.
It's a good way to save time. It makes me a better cook. I'm satisfied with this product. I love it.
the size is excellent for a family of 4. the time to cook is reduced by 4times. easy to clean and food tast stay in the  food
I love this cooker. I can cook my meals  in less time, therefore saving on my propane in the motor home. Works great.
Extremely easy to cook in. Extremely easy to clean. In short, a delight for a single person who doesn't wish to spend too much time scrubbing and standing by the gas.
i love using a pressure cooker because it makes meats tender...also is faster too cook with. I got for camping and keep my big one at home. Also as its aluminum it's much lighter weight for the trailer.
I'm used to cooking slowly, and waiting forever to get my food... Now I don't know what to do with all the extra time! I am going to buy another one so that I can cook a side dish quickly as well.
I really wanted to use this for sterilizing pint canning jars, but it is not tall enough. however, it does cook an artichoke or two, and they get done fast, and they are cooked all the way through. everything cooks faster under pressure
