I had no idea!

Still I'd spring for and Instant Pot, lots of versatility there.


There are no microwaves with two magnetrons.>>

You also need to review the definition of the word, "theory.">

I have two Power Quick Pots that I use all the time. To cook beans, I put about an inch of water into the pot, then put my dry beans and water into a 4 cup Pyrex measuring cup that I place inside. It makes cleanup easier. I do the same with rice. I also use the unit to salvage whatever is left on the Costco chicken after about 5-6 days. I had two, but gave my son one, then realized that it would be useful to have a second one, so I bought another lightly use one.

I stand corrected, but what I want to know is how they keep the 2 magnetrons from frying each other.

A little more info here. It is a 220V commercial unit.

Countertop Commercial Microwave

The "commercial unit" that I covet is a pressure fryer, but unless I won the Powerball, I'd never buy one.

I bought the Power Quick Pot at Costco a few months back and have had time to really see the ins and outs of this pressure cooker. It is half the price of the Instant Pot, but is it half the quality? I also demo a new accessory to use with the pressure cooker, that will make steaming food much easier!

$39.99 is a great price.
