There seems to be a bit of confusion on this thread. Instant Pot is the name brand of the most popular electric pressure cooker. There are other brands as well (Farberware, etc), that are electric pressure cookers, but they aren't actually Instant Pots. A major benefit to the Instant Pot brand is that the liner is stainless steel rather than non-stick. The non-stick liners seem to have issues after a few months, according to reviews.
I love my Instant Pot! In fact, I love it so much that I bought a second one. Both of mine are the DUO-60 model. DUO means it has both high and low pressure, so I can make yogurt on low pressure. 60 means it's the 6 quart model. The 8 quart model wasn't yet released when I bought both of mine. I make a ton of stuff in it...dried beans, white rice, brown rice, no drain mac n' cheese and other pastas, potatoes for mashing, stews, soups, chili, whole chickens, roasts, shredded pork, corn on the cob, etc. I'm probably forgetting a lot of things I've made. My friend makes cheesecakes in hers, but I haven't tried that yet. I bought both of mine on Amazon. Just search for Instant Pot Duo-60 or Duo-80.
