I'm a complete pressure-cooking novice, never owned one or cooked with one until I bought this.  First day I had it I decided to make the pot roast per the instructions in the booklet.  Browned it in the pot, added the liquid, some onion and one of those pot roast seasoning packets from the store, brought it up to pressure, and 45 minutes later it was done.  I have made roasts in the slow-cooker and my oven before, and never ever have they been as good as the one from the pressure cooker.  Fall-apart tender, absolutely perfect.  I'll sheepishly admit it was even better than my grandma used to make and she made a roast every Sunday for 40+ years.  Once the meat was done I removed it and added some cut up carrots and potatoes and they cooked in less than five minutes.  You'd never know they weren't cooked all day in a slow-cooker.  I told myself that if I really liked pressure-cooking that I'd eventually upgrade to a more expensive one but I like this one so much I don't see that happening any time soon.
