Similar to Instant Pot but the user interface is cumbersome
November 22, 2018
The Mueller pressure cooker is very similar to the instant Pot. The lid, gasket, pressure release system, heating system and stainless inner pot look very close. Note that the vessels are not interchangeable between the Instant Pot and the Mueller, which will prove an issue if you want to purchase a second one: Instant Pot accessories are easy to find, but good luck finding a Mueller pot.
Performancewise, the Mueller did a good job; I made my favorite Thai chicken dish and it came out perfect in the same amount of time as it does in my Instant Pot. Sauteeing worked well, too. However, the Mueller does not have an easy instant visual pressure confirmation like the Instant Pot does (the pop up thingie is hidden inside a well in the handle)
The user interface is where things go really bad. I found the program selector and the variations extremely frustrating. Choosing a simple manual program should not be so complicated!
Then, I figured what the hell, instead of going crazy trying to make sense out of the very terse manual, I'll go through some of the recipes from the booklet and that will teach me how to use the machine.
As you can see from the picture I attached to this review... Not only did Mueller rip off Instant Pot recipes, they didn't even bother reading them, or they would have found multiple instances of their competitor's name as well as Instant Pot-specific UI features (the Mueller does not show "Hot" on the display when it reaches sauté temperature).
If I hadn't already used it and tossed the box, I would return this stupid thing. Do yourself a favor and buy an Instant Pot.
