I bought the Power Cooker at Walmart. The instructions are terrible. What I need to know is how to adjust the time and when to do it. Other than that I have used it a couple of times, once for mac and cheese (won't do that again, we didn't like it), and once for chicken stew which was delicious and once for a pot of beans, also good. If someone has this cooker and could help me resolve the "time" issue I would certainly appreciate it.
