I use to have a pressure cooker years ago, and I used it all the time. It did cook the best fall off the bone meat, and held in all the flavor. I remember at first being afraid of it, but after about the second time, I never was afraid to use it again. It was very safe.
Now days it's mostly my crock pot. I got it when I was still teaching so I could put something on before I left and it would be done when I returned home.
