My Mom always told me horror stories about pressure cooker, but I really wanted one after listening to my friend's successful experience with it. I got this 4-quart one several weeks ago, and I am super happy with it!!  I have been pulling an entire beef top round and pork shoulder straight out of FREEZER to cook in pressure cooker, and I was able to serve dinner in an hour.  It's perfect for a poor planner like me.
