My sister picked this one out and after watching her use hers, I couldn't wait to get my own. I've only used it once - but it was the best stew I've ever made and it took 10 minutes to cook the whole dinner. I've always been afraid of using a pressure cooker, but after learning how to use one and now using it (okay, I called my sister 5 times while using it to make sure I was dong it all right!), I don't know how I've lived without one all these years. I'm learning to be less afraid, but I will always respect the power of a pressure cooker. I follow all of the tips that come with it and that my sister pointed out - plenty of water and make sure the valves are all clean and clear. Excellent product for fast, delicious meals.
