I’ve been using the IP 9-1 Duo Plus for about three years and absolutely could not not survived without it, as I have very limited mobility and can’t stand to watch & stir. have also been researching on getting another, they all seem to cook the same, each model varies with some kind of improvement which is great but beware of what you choose as randomly the manufacturer decides to retire certain models so that if you need to buy new rings or accessories they are no longer provided! Even the newer models like the Rio wide, I was considering purchasing however but wanted another inner pot as because I store an entire pot of soup to eat throughout in the refrigerator I have not found anywhere to purchase another
7 1/2 inner pot. Lot's to consider, however they have certainly helped me as I'm almost 80 yrs and by being able to sit and prepare dump and go meals once the lid is locked and time elapses a healthy tasty meal is complete.
