Who it's for
Fits anyone who wants one countertop appliance to replace a toaster oven, air fryer, and rotisserie for daily use, and who has enough counter clearance around the rear vent. Less suited to anyone expecting oven-fast preheat times or planning to run it unattended for long stretches.
What buyers say

Daily users are largely enthusiastic, with several saying it replaced their conventional oven for everyday cooking and praising how it remembers previous time and temperature settings. Complaints center on longer preheat and cook times than a standard oven, hot air venting from the rear that needs clearance, and at least one report of the control knob failing after roughly three years of regular use.

Questions about the Instant Pot 140-4002-01
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
How does the Instant Pot Omni Plus air fryer mode compare to its oven modes?
Reviewers who use all the functions say air fry is the standout, and note it can run hotter than the dial suggests, recommending starting around 360 degrees for tasks a regular oven would run at 450.
Will a whole pizza fit inside the 140-4002-01?
Yes, the unit is sized to fit a 12-inch pizza, and reviewers confirm using it for full-size pizzas.
Is there anything to watch out for with placement?
Yes, it vents hot air from the rear, so reviewers recommend leaving clearance behind the unit rather than pushing it flush against a wall or cabinet.
