My ds has the Instant Pot one. He said he’s very happy with it and uses it fairly often, generally for fish, chicken, or eggs, and once for infusing gin. He recommends reusable silicone bags rather than the plastic ones. A friend of his has the Joule version, which is pricier and works with a phone app, but my ds thinks the IP one does a good job for less money. Two other things he mentioned—it’s relatively compact for storage, and if he’s running late, it holds the food’s temperature so he”s not tied to a set time.
