Different brands can't be used universally, even pots with the same brand, model and batch are not recommended to be used universally, because the molds will be replaced in stages due to wear, and the new pots produced after mold replacement still need to undergo strict technical tests again. That is to say, if pots and lids with the same brand and model but different molds are produced, there may be subtle differences, which generally will not have much impact and may also reach universality.
