Like everything, you need to follow directions and use care. Don't be afraid of a pressure pan if you lister to the sound the jiggling gauge makes and adjust the flame till it is gently rocking and not going crazy. When the time called for in your recipe is passed you can lower the pressure more quickly by placins a wet cool cloth on top of the lid and lettind the pressure escape. Don't try to cook very starchy foode as the resultins gluey juice will clog the vent. Use the rack included with the unit when you are cooking meat.
I live above 6000 ft and love the ease of cooking this way.
