My daughter gave DH and I one for Christmas a few years ago. It is the smallest one they make and is perfect for the 2 of us. I use it about 1x monthly sometimes more. I have worked with pressure cookers all of my life. This small electric one works the same way as any pressure cooker. I love the small size. I made a venison roast in it last week it was out of this world! It is an easy to use pressure cooker. The best rice cooker too.
